II.                ProductDescription

Theseproducts used PVC resin as base materials, and added nanometer conductivecarbon black as filling, by mixing, plasticizing, pelleting, and finished aspellets. These products have very good conductive and processingcharacteristics. And it mainly substituted the graphite coat structure.

In theformula, it decreased the affect of plasticizer to conductive carbon black bythe technology of toughness reinforcing. At the same time, reduced the affectof materials low temperature and processing properties, because adding masscarbon black in the products. And we selected suitable low temperatureadditiver and rheological agent to improve the PVC materials, and made it hasgood integrated properties.  

III.              Processing

Use singlescrew extruder to process, suggest to put one layer 60/80 strainer.

Thefollowing temperature(℃) profile of extruder is recommended:

Q:What glue is best for sticking glue
Determination of the above requirements of choice such as small area bonding glue is generally used, quick drying glue, is instant glue, together with surface treatment agent PP/PE/POM for use. The first treating agent for cleaning the surface, you can achieve a good bonding effect. Of course, the cost is not low. But super adhesive the adhesive surface damage to. Recommended adhesive: ABS material can be used ABS special glue HR-700, PP, PE, PA material availablePP, PE sleeve special glue HR-736
Q:What material is better for plastic cups?
There are PC, AS, PP.TRITAN (, PCTG) and ECOZEN (Korean SK). PC is banned in the bottle and in some European and American space cups because of the effects of BPA on the baby reproductive system. AS too crisp; PP cost-effective, environmental protection, transparency and feel bad. TRITAN and ECOZEN are currently in the domestic manufacturers do not have the domestic market, export orders, but also environmental protection, does not contain BPA, transparency and feel and equal to PC, the price is high, the daily use of PP for advice can, or simply use glass.
Q:How many years will it take for a plastic bag to rot?
Biodegradable plastic bags are not automatically degraded under any conditions. According to reports, biodegradable plastic bags still contain plastic ingredients, only biodegradable plastic bags are buried in the ground, at a certain time and temperature can be degraded.
Q:The concept, classification and distinction of modified plastics and plastic raw materials.
Concept: modified plastics, refers to the base of the general plastics and engineering plastics, after filling, blending and enhancement processing method of modification, improve the performance of flame retardant plastic products, strength, impact resistance, toughness.
Q:What are the distinguishing features of plastics? What is their chemical name?
PE) and linear low density polyethylene (LLDPE). Among the three, HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE have better flexibility, impact and film forming properties. LDPE and LLDPE are mainly used for packaging film, agricultural film, plastic modification, etc., and HDPE is widely used in many fields, such as film, pipe, injection, daily necessities and so on.
Q:What are the materials for plastic bottles?
It has been reported that eating foods contaminated with polyethylene molecules for a long time can cause dizziness, headaches, nausea, loss of appetite, memory loss, and even anemia. Therefore, the use of plastic bottles vinegar, human health has no harm. Therefore, the family should use glass ware instead of plastic products, such as condiment products. The use of plastic products should pay special attention to, do not touch vinegar, detergents, etc., to avoid direct sunlight, high temperature, etc., so as not to occur chemical reactions. In addition, when you buy plastic tableware, you should choose goods with PE (polyethylene) or PP (polypropylene) mark, decorative patterns less, colorless, tasteless, smooth surface of plastic products.
Q:How to make up the holes in the plastic basin, and the method is simple and durable
Attention to cover the leakage of copper can be, not too large, gently ironing, do not burn thoroughly, can fuse together on the line.

Q:What are the benefits of plastic bags? What's the disadvantage?
Advantages of plastic bags: the invention of plastic bags brings convenience and sanitary life for human beings. The emergence of plastic bags will also reduce food waste, the nature of the fungusproof mold also protected the health of human beings, plastic bags are used instead of other packaging materials such as paper, glass, cans, etc., to reduce energy loss;
