PPS-CF30 | 30% Carbon Fiber Reinforced Polyphenylene Sulfide
PPS-CF30 is a high performance, semi-crystalline thermoplastic composite reinforced with 30% carbon fiber, engineered for structural stability, thermal endurance, and chemical resistance in the most demanding environments. This formulation balances stiffness and strength with excellent dimensional stability and thermal tolerance, making it a premier choice for replacing metals in high-precision, high-temperature applications.
Compared to unfilled PPS or lower fiber filled grades, PPS-CF30 delivers significantly enhanced mechanical properties, including elevated tensile strength, flexural modulus, and creep resistance—without compromising its excellent resistance to chemicals and thermal degradation. The result is a material capable of long-term performance under static or dynamic loads in chemically aggressive and high heat conditions.
PPS-CF30 is especially well suited for applications across automotive, electronics, aerospace, and industrial sectors that demand lightweight, thermally stable materials capable of handling heat, stress, and harsh environments.

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.
