High temperature nylon (PPA) is a specialty engineering plastic produced through polycondensation reaction between aromatic dicarboxylic acids and aliphatic diamines. Its composites feature a heat deflection temperature exceeding 265C and long-term service temperature above 180C. These properties fully meet the high-performance requirements of electronic and automotive components, including miniaturization, thin-wall design, precision, lightweight, and heat resistance. PPA demonstrates extensive application prospects in electronic connectors, smart grid inverters, LED reflector brackets, and automotive sectors.
