High temperature polymers, also known as high temperature plastics, are melt processable plastics having an operating temperature over 150°C. The global demand for high temperature thermoplastic is rapidly growing in plastics market. Compared to commodity plastics, they provide superior thermal stability, durability, wear resistance, chemical resistance, and mechanical performance that are very close to metal.
High temperature polymers are able to operate at elevated temperatures because of their rigid polymer chains while many polymers lose performance over time at high temperatures. Common kinds of high temperature thermoplastics include LCP, PA6T, PA9T, PA46, PA66, PPS, they are mainly used in the industries of automotive, aerospace, electrical and electronics, medical, etc.
