Technical Field

[0002] PPA (Polyphthalamide), also known as polyphthalamide, is a high-performance engineering plastic material. It is renowned for its exceptional thermal, electrical, physical, and chemical resistance properties. PPA is primarily produced through the polycondensation reaction of phthalic acid and o-phenylenediamine. Its molecular structure encompasses both semi-crystalline and amorphous states, endowing PPA with exceptional mechanical and heat resistance. However, its physical form and processing conditions must be strictly controlled during processing and use. If PPA material agglomerates before or during processing and cannot be effectively broken down, it can lead to a range of problems, seriously impacting product quality and production efficiency.
