PPS-LCF10 | 10% Long Carbon Fiber Reinforced Polyphenylene Sulfide
PPS-LCF10 is a high performance, semi-crystalline thermoplastic composite reinforced with 10% long carbon fiber, engineered to combine enhanced mechanical strength, superior dimensional stability, and exceptional chemical and thermal resistance. Compared to short fiber grades, PPS-LCF10 leverages long carbon fibers (LCF) to deliver improved load transfer, fatigue resistance, and creep performance, especially in structurally demanding environments.
With its optimized balance of strength, weight, and processability, PPS-LCF10 is ideal for high precision parts requiring long term performance in thermally and chemically aggressive applications—while offering lower fiber content and easier processing than higher LCF reinforced composites.
Core Performance Highlights

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.
