There are many ways of making polyethylene, the most common of which is the polymerization of ethylene at temperatures of 200~300 C and 1000~2000 atm. In polyethylene, no other substance is doped. This low density polyethylene obtained, soft texture, for sunlight, air, water and chemical reagents, have high stability, so no external stabilizer, plasticizer, stabilizer and plasticizer are mostly toxic or highly toxic.
Q:Are common plastic products in daily life, what are the materials?
For example, the Chinese name of PP is polypropylene, and the English name is polypropylene. In the front, a P stands for "poly-", "poly", "propylene", and "P" means "propylene".

Q:What are the shapes of plastic parts?
The shape of the plastic parts should meet the requirements of the use of the premise, so that it is conducive to forming, in particular, should not try to use the lateral core pulling mechanism, so the design of plastic parts should be avoided as possible lateral concave convex shape or side hole.
Q:How do I see if the plastic cup is qualified?
