PPA-CF30 | 30% Carbon Fiber Reinforced Polyphthalamide
PPA-CF30 is a high-performance, semi-crystalline engineering thermoplastic reinforced with 30% short carbon fiber, designed for maximum mechanical strength, rigidity, and dimensional stability in demanding thermal and chemical environments. With a high fiber loading, it delivers metal-like performance while maintaining PPA’s excellent chemical resistance and thermal endurance.
Compared to lower fiber content grades such as PPA-CF10 and PPA-CF20, PPA-CF30 offers significantly improved creep resistance, load retention, and warpage control, making it ideal for precision-engineered components operating under high stress and temperature cycling.
Core Performance Highlights
Mechanical Properties
Carbon Fiber Content: 30% (short chopped fibers, densely distributed)
Tensile Strength: ~165–180 MPa
Flexural Modulus: ~14–15 GPa
Elongation at Break: ~0.8–1.2%
Notched Izod Impact: ~35–45 J/m
→ The high CF content gives PPA-CF30 exceptional stiffness and structural integrity, ideal for metal replacement applications requiring tight tolerances and mechanical durability.
Thermal Resistance
Heat Deflection Temperature (HDT): ≥ 270 °C
Continuous Use Temperature: Up to 230 °C
→ Excellent for long term heat exposure, such as engine compartments, electric drive systems, or industrial machines under continuous thermal stress.
Environmental & Chemical Durability
Moisture Absorption: ~0.08–0.12% — very low, enabling stable part geometry
Chemical Resistance: Outstanding — resists fuels, oils, coolants, acids, bases, and industrial solvents
→ Delivers reliable mechanical and dimensional stability even in humid or chemically aggressive environments.
Processing & Manufacturing
Molding Methods: Injection molding
Surface Finish: Matte to rougher texture; fiber exposure likely
Tooling Requirements: Requires high hardness steel molds; increased tool wear expected
→ Lower flowability than CF20, but still suitable for structural parts with controlled wall thickness. Processing should be optimized to preserve fiber orientation and achieve optimal mechanical performance.
Target Applications
Automotive & Mobility
Structural brackets, pump housings, transmission supports
→ Delivers high strength, thermal resistance, and chemical durability for metal replacement in under hood systems.
Electronics & Electrical
Battery frames, connector blocks, inverter housings
→ Provides mechanical rigidity and dimensional control under heat, current, and vibration.
Industrial Equipment
Gear covers, sensor frames, robotic arms
→ Ideal for high load, high precision parts operating in corrosive or high temperature industrial settings.

Strength between PPA and PPA-CF
PPA-CF (carbon fiber reinforced) offers significantly higher mechanical strength and rigidity compared to standard PPA. The addition of carbon fiber enhances tensile strength, flexural strength, and wear resistance, making PPA-CF more suitable for heavy loads and extreme environments. While standard PPA is suitable for medium-load and conventional applications, PPA-CF provides superior performance for more demanding industrial conditions.
