20% Carbon Fiber Reinforced PPS Granules

20% Carbon Fiber Reinforced PPS Granules combine the inherent chemical resistance, thermal stability, and dimensional integrity of polyphenylene sulfide (PPS) with the strength, stiffness, and wear resistance imparted by short carbon fiber reinforcement. This composite exhibits excellent mechanical performance even at elevated temperatures, along with low creep and outstanding fatigue resistance. Industries such as aerospace, automotive, and electrical engineering use it for high-precision, high-load components where corrosion resistance and dimensional stability are critical. Applications include structural housings for under-the-hood automotive electronics, corrosion-resistant pump and valve components, and heat-dissipating casings for electrical systems. In research and innovation, these granules are vital for producing lightweight, high-performance prototypes, particularly in sectors focused on replacing metals with advanced polymers without sacrificing mechanical integrity. The combination of PPS’s chemical resilience with carbon fiber’s reinforcement enables long-life, high-reliability components, making this composite indispensable in next-generation engineering solutions.
