Doors and Windows of new material WPC composite profiles

In recent years, WPC has become an indispensable architectural ornament materials, which plays an irreplaceable role in many application areas. Especially in the industry of building doors and windows, the use of plastic profiles and wood has been in intense competition. When high quality wood products is more and more favored by people, when log products become more and more popular in the city, the rate of deforestation is also growing fast, which sounds an alarm for the depletion of natural resources. Fortunately, the development of plastic profile industry largely replaces the wooden doors and windows, and alleviates the ecological crisis to some extent. However, it also brings some unavoidable defects, such as the texture and color of plastic material cant surpass the wood products, so the price/performance ratio is greatly reduced.Then, the new material WPC emerges at the right moment.
When the WPC composite profiles are successfully applied to building materials, this new material reaches the function of wood and plastic and then replace them. People illustrate the superiority of WPC through functional comparison among the WPC composite extrusion products, plastic products and wood products. First of all, through the comparison between WPC composite extrusion products and wood products, after the WPC composite material goes through extrusion process, the finished products bear a strong resemblance to the appearance and texture of wood, and has the same processing performance, construction performance as wood. The product density in between 600 and 1000kg/m3, which is different according to the filler content of wood fiber and the degree of frothing percentage, generally around 600~800kg/m3, very close to the wood. The water content is about 2%, while the water content of wood is between 12% and 13%, compared with WPC composite material, it has better water resistance, corrosion resistance and other functions, and there is no defects of natural wood, such as cracks, warping, scar knot, obvious color difference etc.. At the same time, there will be a fatal weakness for wooden doors and windows besides mechanical and physicochemical injury, that is the damage of insect attack, such as termites, beetles and other pests. However, the WPC composite section contains a variety of chemical agents, which can resist pests. In addition, the section design of extruded products is quite flexible, which can design decorative decoration structure and various function structures, while the function structure and decoration structure of wood products are often limited by processing method, making many decorative effects difficult to achieve. Clearly, these are the points WPC composite extrusion products are superior to wood products.
Secondly, through the comparison between WPC composite extrusion products and ordinary plastic material, the WPC composite material has most advantages of ordinary plastic material, such as anti-flaming, anti-aging, meanwhile has other advantages that ordinary plastic material can not replace, such as color, texture, light weight and other quality properties, able to nail, drill, saw, dig, paint, adhesive and other processing performance. However, the extrusion products of WPC composite material has poor welding performance, which is basically not suitable for welding. Therefore, the doors and windows assembly need to adopt screw connection, a serious deficiency. However, the use of WPC composite extrusion products can be site construction, which bring a lot of convenience for the transport and installation of doors and windows, to a certain extent making up the defect. From the above two comparisons, we can see WPC composite material owns most properties of wood and plastic, and is able to integrate main properties of the two in one set, meanwhile it also has its own unique function. The most important is that the use of WPC composite material can save energy to a great extent, reduce the loss of non renewable resources and maintain the balance of natural ecology.
Compared with plastic profile and wood, WPC composite has unparalleled advantages, which is energy saving, environmental protection. Definitely it will have a wide range of application prospect. With further improvement of production technology for WPC composite extrusion products and wide-range promotion of production technology, WPC composite profiles can replace the position of plastic and wood products, and gradually become up-and-coming youngster in the market of architectural ornament.

Development of CPE 135A

Chlorinated polyethylene resins and elastomers (CPE) exhibit excellent physical and mechanical properties, including resistance to chemicals, oils, heat, abrasion, and weathering; low-temperature performance; compression-set resistance; flame retardancy; high filler acceptance; and tensile strength. These polymers are used as the major and/or minor component in a wide assortment of applications in industry. The largest application for CPE is as an impact modifier. Other important end-use applications for CPE include wire and cable jacketing, roofing membranes, geomembranes, automotive and industrial hose and tubing, coatings, molded shapes, extruded profiles, and use as a base polymer.

China now accounts for 98% of total world production (in 2008, China accounted for 83% of total world production). Largely as a result of the significant capacity increase in China, there is currently a wide surplus of capacity worldwide, with the global operating rate estimated at 55-60% in 2014. China is also the largest CPE consumer in the world. By far, China continues as the world leader in terms of chlorinated polyethylene nameplate capacity. The last 25 years were clearly marked by a rapid buildup of CPE capacity in China. China is the largest exporter of CPE; most exports are probably to the United States, Europe, and other Asian countries. There are many small-volume CPE producers in China; it is likely that some of these producers will shutter operations as a result of the current overcapacity situation as well as the generally competitive market.

Resin (mainly PVC) impact modification is tied very closely to the general health of the building and construction sector. Another factor that comes into play is competition from other impact modifiers, such as acrylics and MBS. The global market is forecast to grow at an average annual rate of about 4.5%.

2016年10月30日星期日

Loss to be Caused by Poor CPE 135A in PVC Products Processing

Chlorinated Polyethylene (CPE) is chlorinated from High-Density Polyethylene. As a kind of PVC processing modifier, chlorine content of CPE is 35-38%. Because CPE has performances of weather resistance, coldness resistance, oil resistance, flame retardancy, impact resistance, chemical stability and good compatibility with PVC Resins, CPE has been the most widely used impact modifier. In general, performances of CPE are determined by two main factors as below:-

1. HDPE’s Molecular Structure

Molecular structures and performances of PE homopolymer HDPE have certain differences due to different workmanship used for the polymerization of PE, thus performances of CPE chlorinated from HDPE with different properties are also different. Therefore, CPE manufacturers must choose suitable HDPE in powder type designed for the production of quality CPE Resin.

2. Chlorination Conditions

As PVC impact modifier, CPE is usually manufactured with the aqueous-phase suspension chlorination method. The main conditions of such method involves light energy, dosage of initiator, reaction pressure, reaction temperature, reaction duration and neutralization reaction conditions. The theory of the chlorination of PE is simple, but the mechanism of chlorination is complicated.

There are plenty of poor CPE on the market. In general, poor CPE include two major type, one is manufactured by unqualified manufacturers with under-developed chlorination method, while the other is CPE adding some Calcium Carbonate powder or talcum powder as a way of unfair competition.

Regarding the former poor CPE, buyers can avoid loss by purchasing those manufactured by qualified and well-known manufacturers. But for the latter poor CPE, many people don’t have enough knowledge for it.As we all know, the prices of Calcium Carbonate and Talcum Powder are 400-500RMB/Ton, while CPE is 8000-8500RMB/Ton. Some illegal manufacturers add some cheap materials as filler and sell at a rate lower than market price to earn market shares. Generally, the price of this type of CPE is 7000-8000RMB/Ton even much lower to 5000-6000RMB/Ton.
If such poor CPE is used in PVC products processing as impact modifier, the dosage of CPE will have to increase for the purpose of strengthening the flexibility and impact strength, resulting in the increase of plasticization time and decrease of equilibrium torque. The above-mentioned matters will lead to the decrease of overall performances and increase of scrap rate. Therefore, disadvantage of poor CPE is obvious.

Matters Needing Attention to Calcium Zinc Complex Stabilizer

There are many kinds of complex PVC Stabilizer on the market. PVC Stabilizers common in the market include Lead Based Stabilizer, Ca-Zn Complex Stabilizer, Ba-Cd-Zn Complex Stabilizer and organic Tin Stabilizer, etc. Calcium Zinc Complex Stabilizer is generally a kind of shallow yellowish or yellowish-brown oily liquid. It has excellent heat stability and sulfide resistance. It can be blended with epoxidized plasticizer to strengthen heat stability properties. And it can be used to activate foaming agent. What are matters needing attention in the production of PVC finished products?

1. Common solid Calcium Zinc Complex Stabilizer is not suitable for transparent cable & wire making, so specialized Ca-Zn Stabilizer shall be used. Manufacturers just need to add a certain dosage of solid Calcium Zinc Complex Stabilizer in their formula for their PVC products making and no lubricant will be needed. In real production situations, a certain quantity of Stearic Acid, PE Wax or Paraffin Wax shall be added to adjust the plasticization in processing due to different formula design and different equipment configuration. Under some occasions where PVC products need to contact with bare copper, much attention shall be paid to the aerugo resistance property.

2. If some other type of PVC Stabilizers are used for PVC cable & wire, all relevant equipment and surroundings shall be strictly cleaned to protect finished PVC cable & wire from outside pollution.

3. Different types of solid Calcium Zinc Complex Stabilizers shall be used for different types of Calcium Carbonate filler and products of different colors. In general, solid Calcium Zinc Complex Stabilizer compatible with light Calcium Carbonate and suitable for white finished products is not suitable for dark and black products making. Therefore, manufacturers should have a clear knowledge of properties of heat stabilizers in the selection of proper PVC Stabilizer and make the formula design as per real production situation.

4. If Calcium Zinc Complex Stabilizer is used together with epoxidized soybean oil, it will have a better effect. If a big quantity of chlorinated paraffin is used, the heat stability of some Calcium Zinc Complex Stabilizer will be badly affected.

Advantages of PVC Floor over Marble Floor and Wooden Floor

Tile and natural marble are very rigid materials and their surfaces are very smooth. So its inevitable that people may feel stiff walking on such floors and people will slip easily when these floors get wet. Therefore, PVC floor has its own advantages of both rigidity of marble and softness of polymer materials. We will feel comfortable walking on PVC floor and people wont slip easily because the frictional resistance on its surface will become more higher when it gets wet.
Wooden floor is very expensive. And it will be out of shape easily when it get damp and it will crack and shrink when get dry, so the joints between wooden floors will be wider. If wooden floor is not maintained properly, it will easily get mildewed and damaged by worms. Compared with wooden floor, PVC floor wont expand when heated or got damp, and it has excellent properties of mildew resistance and moth proof, so the maintenance of PVC floor is very easy.
Calcium Carbonate powder contained in PVC floor determines good compressive strength of PVC floor. Added synthetic resins gives PVC floor a certain softness. Thus PVC floor wont be easily broken like tiles and marble due to its excellent impact resistance. UV abrasion-resistant coating is used in PVC floor. Abrasion resistance property of PVC floor will be strengthened with the increase of hours of use.

The Latest Trend of PVC Resin Price

As indicated by statistics published by relevant authority, the average market price of PVC Resin SG-5 in China was 5870RMB/Ton before September 5. But the latest average market price was already 6470RMB/Ton on September 22, 2016. In past half month, the average price of PVC Resin SG-5 is 600RMB/T higher. What are the reasons for that? Lets check it together.
Historically Strictest Environmental Supervision Campaign in China
The issue of  Environmental Supervision Campaign can be dated back to the July. From the middle of the July to August 19, Chinese environmental supervision authorities launched a round of very strict “Environmental Supervision CampaignMany supervision groups were sent to eight provinces to carry out the supervision missions in Inner Mongolia, Jiangsu Province, etc.
During the Environmental Supervision Campaign, Ministry of Environment carried out strict investigations to manufacturer of limestone, which is the raw material used for calcium carbide production. At the same time, part of small-and-medium sized carbide factories were punished and dealt with.
Above-mentioned supervision campaign resulted in shutdown of some calcium carbide factories and decrease of carbide production capacity. As a result, calcium carbide on the market reduced accordingly, thus making PVC Resin SG-5 price keep going up.
The first round of  Environmental Supervision Campaign ended not long before. The second round of  Environmental Supervision Campaign will be launched in the October.
As the report published by Ministry of Environment, the second round of  Environmental Supervision Campaign will be carried out mainly in Shandong Province. Speaking of Shandong Province, it ranks top in the production of all kinds of chemicals. There are 8 PVC Resin manufacturers in Shandong Province, with the total productivity of 2,230,000 tons per year, accounting for 11% of the total productivity in China. Such supervision campaign will exert some effect on chlorine-alkali enterprises in this area. It will probably affect the PVC Resin market.
Adjustment in Policies and Regulations of Land Transportation
In the beginning of the September, China's Ministry of Transport published a series of new regulations to tighten the administration of land transport. From now on, overload will be strictly examined and punished in violation of relevant policies and regulations. Measures taken by shipping forwarders are as below:-
1. If the weight of goods is more than 10 tons, no LCL operation will be accepted;
2. If the weight of a 40GP is more than 25 tons, no trailer service will be provided;
3. 40HQ Container services will be suspended;
As a result, cost of land transport will increase by 20%-50%. For international trading companies, it will be a big cost.
Price of Calcium Carbide at High Level
In the beginning of 2016, the price of Calcium Carbide kept stable at a relatively low price. However, the price of Calcium Carbide has increased rapidly since the second half of July.
As the statistics, the average market price of Calcium Carbide kept stable at 2400-2580RMB/Ton in East China in July 21. But now it already goes up to 2850-3030RMB/Ton in past two month.

Low Social Inventory Stock and Supply of PVC Resin in Shortage
Statistics of Social Inventory Stock in Main Regions of China

As the statistics published by www.zhaosuliao.com, by September 18, social inventory market in main Regions of China decreased rapidly, fell 32.72% year on year and 10.22% month on month.
PVC price keep going up and trade of PVC Resin SG-5 is heating up in this week, so the social inventory stock will decline further.  
In conclusion, the price of PVC Resin SG-5 will keep at a high level due to tightened environmental supervision, adjustment of regulations of land transportation and low inventory stock before the Chinas National Holidays.
Extra News
As we all know, the bankruptcy of the biggest Korean logistic company--Hanjin Logistics brought big volatility to the whole international trading market. K-Line company, as a member of CKYHE League, is also stuck in deep debt crisis. As is predicted, it will not be very far that K-Line company will be purchase by some powerful financial group.
It is reported that Singapore Effissimo Foundation has already got more than 30% of stock rights of K-Line. Effissimo Foundation only held 6.2% of K-Lines stock rights before. However, the latest information showed that stock rights of K-Line held by Effissimo Foundation has increased to 37%.

K-Line republished a financial report in June 30 and the report showed that their company suffered a loss of 26.79 billion yen (about 260.36 million USD) in the first quarter of this year. However, K-Line earned 10.19 billion yen in the first quarter of last year.

Meanwhile, K-Line announced that the total income of the first quarter was 244.59 billion yen, declined 27.% compared with the first quarter of last year. And they predicted that this financial year they will suffer a total loss of 45.5 billion yen by March 31, 2017.

“Consecutive losses of K-Line make investors and market uneasy and their businesses will have to be simplified.” said Ryota Himeno, famous analyst of Citi Group.
