Polybutylene Terephthalate (PBT)
Polybutylene terephthalate (PBT) is a polyester made by the condensation of terephthalic acid and 1,4-butanediol. It is an important thermoplastic polyester and one of the five major engineering plastics. Polybutylene terephthalate is a milky white, translucent to opaque, semi-crystalline thermoplastic polyester with high heat resistance. It is not resistant to strong acids and alkalis, but…

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…
