PPS-CF50 | 50% Carbon Fiber Reinforced Polyphenylene Sulfide
PPS-CF50 is a top tier, semi crystalline thermoplastic composite reinforced with 50% carbon fiber, developed for extreme mechanical, thermal, and chemical performance. This ultra high carbon fiber content delivers maximum stiffness, dimensional accuracy, and tensile strength, making it an optimal metal replacement in structural applications exposed to high loads, elevated temperatures, and corrosive environments.
Compared to PPS-CF30, PPS-CF40, and unfilled PPS, PPS-CF50 offers substantial improvements in flexural modulus, tensile modulus, and creep resistance, while maintaining PPS’s hallmark thermal stability and exceptional chemical resistance. It is engineered for critical, long term applications where rigidity, strength, and precision are non negotiable—even under continuous stress and thermal cycling.
Ideal for demanding sectors such as aerospace, automotive, electronics, and industrial machinery, PPS-CF50 enables lightweight design without compromising performance or reliability.

Friction coefficient of PPS-CF
The friction coefficient of PPS (Polyphenylene Sulfide) typically ranges from 0.3 to 0.45, while PPS-CF (Carbon Fiber Reinforced Polyphenylene Sulfide) has a lower coefficient, generally between 0.2 and 0.35. The addition of carbon fiber improves hardness, wear resistance, and reduces friction, making PPS-CF more suitable for high-load, high-temperature, and high-friction applications.
