Polypthalamide, an engineering thermoplastic, is a member of the nylon family with excellent high temperature properties (heat deflection temperature of 280oC and a continuous use temperature of 170oC).

Polypthalamide also provides excellent resistance to chemicals including fuels and glycol. Thanks to these mechanical properties, polypthalamide has been refined and developed for use in glycol-based, high-temperature applications—specifically automotive radiators.

 Temperature gradients and temperature cycling are the biggest challenges for materials used in cooling systems, and polypthalamide has proven to be up to these challenges in automotive cooling systems around the world.

 Polypthalamide also has good chemical resistance properties, particularly with respect to glycol-based coolants commonly used in automotive and injection mold cooling systems. Thus, polypthalamide is an ideal material for use in thermoplastic injection mold cooling systems.
