Polyphenylene Oxide (PPO)
Polyphenylene ether is a high-strength engineering plastic developed in the 1960s. Its chemical name is poly 2,6-dimethyl-1,4-phenylene ether, abbreviated as PPO (Polyphenylene Oxide) or PPE (Polypheylene ether), also known as polyphenylene oxide or polyphenylene ether. Basic Information Polyoxyxylene was produced by General Electric Ashay in 1956 by using cuprous chloride as a catalyst to oxidatively…

Polystyrene (PS)
Polystyrene (PS) is a polymer synthesized from styrene monomers by free radical addition polymerization, and its chemical formula is (C8H8)n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100°C, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as…

Thermosetting plastics
Plastics that are made of thermosetting resin as the main component and are combined with various necessary additives through a cross-linking curing process to form finished products. They are liquid in the early stages of the manufacturing or molding process, and after curing they are insoluble and infusible, and cannot be melted or softened again.…
