Thermochemical and Flammability Properties of Some Thermoplastic and Thermoset Polymersa Review

Abstract

There is an increasing demand both for thermoplastic and thermoset resins which, depending on the application, must exhibit one or more high performance characteristics. The resin chosen for a particular application must not only meet the end requirements but also must have good processing characteristics. High performance thermoplastic polymers and thermoset resins must possess one or more of the following characteristics: good thermal oxidative stability, good elevated temperature mechanical properties, high humidity resistance, good fatigue and toughness properties, and chemical and radiation resistance. In addition to the above properties, the polymers selected must exhibit good fire-resistant properties, especially if the material is intended for use in habitable areas. The material must exhibit the following properties when subjected to various flammability tests: low rate of heat release and fuel contribution, low smoke emission, and low concentration of toxic gases when subjected to a fire environment.
