PPS-CF40 | 40% Carbon Fiber Reinforced Polyphenylene Sulfide
PPS-CF40 is a high performance, semi-crystalline thermoplastic composite reinforced with 40% carbon fiber, designed for superior structural integrity, thermal endurance, and chemical resistance in the most extreme environments. With increased fiber loading, this grade offers higher stiffness, tensile strength, and dimensional control, making it an advanced solution for replacing metals in precision, high load applications subjected to heat, chemicals, and mechanical stress.
Compared to PPS-CF30 and unfilled PPS, PPS-CF40 exhibits significantly enhanced mechanical performance—including elevated flexural modulus and reduced creep—while maintaining excellent thermal stability and chemical durability. This makes it exceptionally suited for long term use under dynamic or static loads in corrosive or high temperature conditions.
PPS-CF40 is ideal for advanced applications across the automotive, aerospace, industrial, and electronics sectors that demand lightweight, high rigidity materials capable of enduring mechanical and thermal extremes.

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.
