Polyphenylene sulfide, commonly abbreviated as PPS (hereinafter referred to as PPS), is a thermoplastic polymer. Its molecular structure is relatively simple, with alternating benzene rings and sulfur atoms forming the main chain. The abundance of benzene rings imparts rigidity to PPS, while the numerous sulfide bonds provide flexibility. It boasts features such as hardness and brittleness, high cleanliness, flame resistance, excellent thermal stability, high mechanical strength, and superior electrical properties.PPS/PTFE, PPS/PA, and PPS/PPO alloys have been commercialized. The PPS/PTFE alloy enhances PPS's brittleness, lubricity, and corrosion resistance, while the PPS/PA alloy is a high-toughness alloy. Glass fiber-reinforced PPS boasts excellent thermal stability, wear resistance, creep resistance, and mechanical and electrical properties over a wide range (temperature, humidity, frequency), with low dielectric constant and low dielectric loss.
