PPS-CF20 Material Overview
PPS-CF20 (Polyphenylene Sulfide with 20% Carbon Fiber) is a high performance engineering thermoplastic reinforced with 20% carbon fiber, offering a robust combination of mechanical strength, thermal stability, and chemical resistance. This formulation significantly enhances stiffness, dimensional stability, and load bearing capacity while maintaining PPS’s exceptional resistance to heat, moisture, and chemicals.
Compared to PPS-CF10, PPS-CF20 provides markedly improved structural performance, superior creep resistance, and better retention of mechanical properties under continuous stress, making it ideal for high-demand industrial, automotive, and aerospace applications.
Mechanical Performance
PPS-CF20 is engineered for applications that require high strength, stiffness, and dimensional control under thermal and mechanical loads.
Tensile Strength: ≥ 135 MPa
Flexural Strength: ≥ 240 MPa
Impact Strength: ≥ 45 kJ/m²
With 20% carbon fiber reinforcement, this material offers excellent structural integrity and performance in load bearing or mechanically active environments.
Thermal and Chemical Resistance
PPS-CF20 retains excellent resistance to thermal degradation and aggressive chemicals, even at elevated temperatures.
Heat Deflection Temperature (HDT): Approx. 260 °C
Long-Term Service Temperature: Up to 200 °C
Chemical Resistance: Excellent — resistant to oils, fuels, solvents, acids, alkalis
The higher fiber content does not compromise PPS’s inherent stability in chemically and thermally aggressive settings.
Wear Resistance and Processing Characteristics
The increased carbon fiber loading improves wear and creep resistance, making PPS-CF20 suitable for continuous operation under friction and mechanical cycling.
Wear Resistance: High — suitable for sliding, rotating, or load bearing parts
Processing Methods: Injection molding, extrusion
Processing Notes: Requires optimized tooling and conditions to preserve fiber alignment and flow
Environmental Adaptability
PPS-CF20 maintains exceptional performance in humid, high temperature, or chemically harsh environments. Its low moisture uptake and dimensional stability ensure reliable long term performance in complex operational settings.
Applications
PPS-CF20 is ideal for high performance parts subjected to mechanical stress, heat, and chemicals:
Automotive: Thermally loaded housings, turbocharger components, pump parts, brackets
Industrial Equipment: Bearings, impellers, gear housings, chemical processing equipment
Electronics: Rigid structural frames, connectors, and thermal management components
Aerospace: High temperature resistant elements and chemically exposed parts requiring precision

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.
