In the family of thermoplastic polyesters is the class of materials known as liquid crystal polymers (LCPs), aromatic copolyesters with a tightly ordered structure that is self-reinforcing. LCP’s generally flow very well in processing, but they have to be thoroughly dried and molded at high temperatures. They also exhibit very high mechanical properties although molded structures tend to be quite anisotropic. LCPs are resistant to most organic solvents and acids. They are inherently flame-resistant and meet federal standards for aircraft interior use.
LCPs have found application in aviation, electronics (connectors, sockets, chip carriers), automotive underhood parts, and chemical processing, and are used to mold household cookware for conventional and microwave ovens.
