Polycarbonate (PC)
Polycarbonate (PC for short), also known as PC plastic, is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the mechanical properties of aliphatic and aliphatic- aromatic polycarbonates are relatively low, which…

Polyoxymethylene (POM)
Polyoxymethylene (POM), also known as acetal resin, polyoxymethylene, and polyacetal, is a thermoplastic crystalline polymer, known as “super steel” or “saigang”. Brief History of Research Around 1955, DuPont Company of the United States obtained homopolymer of formaldehyde by polymerization of formaldehyde. Polyoxymethylene is easy to crystallize, with a crystallinity of more than 70%. The melting…

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…

Polyurethane (PU)
Polyurethane (PU), also known as polyurethane, is a polymer material with excellent mechanical properties formed by the polycondensation reaction of polyols and polyisocyanates.Its synthesis can be traced back to 1937, when Professor Byaer first synthesized a linear polyurethane resin using 1,6-hexamethylene diisocyanate and 1,4-butanediol as raw materials.The main types of polyurethane include polyether, polyester, polyimide,…

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…
