PVC is actually a kind of vinyl polymer, and its material is a kind of non crystalline material. Stabilizer, lubricant, auxiliary processing agent, pigment, anti impact agent and other additives are often added to PVC materials in actual use. It is nonflammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidant, reductant and strong acid. However, it can be corroded by concentrated oxidizing acid, such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contacting with aromatic hydrocarbon and chlorinated hydrocarbon.
PE, with the full name of polyyetylene, is the most simple polymer organic compound. Nowadays, it is the most widely used polymer material in the world. It is polymerized from ethylene. It can be divided into high-density polyethylene, medium density polyethylene and low-density polyethylene according to the different density.
Features: PE is soft and feels waxy. Compared with the same plastic, it is light and transparent. The flame is blue when burning.
