- Tensile Strength: ≥ 250 MPa (Enhanced by 40% carbon fiber reinforcement)
- Flexural Strength: ≥ 350 MPa
- Impact Strength: ≥ 10 kJ/m² (Optimized for high reinforcement levels)
The 40% carbon fiber content provides exceptional stiffness and strength, making PPA-CF40 ideal for the most demanding mechanical environments.
Thermal and Chemical Resistance
PPA-CF40 excels in extreme thermal and chemical environments, offering exceptional heat resistance and chemical stability.
- Heat Deflection Temperature (HDT): Approx. 320°C
- Long-Term Service Temperature: Up to 280°C
- Chemical Resistance: Excellent resistance to oils, fuels, solvents, and aggressive industrial chemicals
The higher carbon fiber content enhances its heat resistance and stability, making PPA-CF40 perfect for high-temperature and chemically aggressive applications.
Wear Resistance and Processing Characteristics
PPA-CF40 is well-suited for applications requiring exceptional wear resistance, especially under heavy friction or continuous motion. Its increased carbon fiber content improves wear properties while maintaining manageable processing temperatures.
- Wear Resistance: Excellent under heavy friction and continuous motion
- Processing Methods: Suitable for injection molding and extrusion, with slightly higher processing temperatures than lower-reinforced grades, but still within typical thermoplastic ranges
PPA-CF40 offers outstanding durability and rigidity, perfect for applications requiring both wear resistance and ease of processing.
Environmental Adaptability
PPA-CF40 offers excellent environmental stability, with very low water absorption, high dimensional stability, and reliable performance in both humid and chemically aggressive environments.
Applications
PPA-CF40 is designed for ultra-high-performance applications requiring superior mechanical strength, thermal stability, and chemical resistance. Typical applications include:
- Automotive Industry: High-strength engine components, structural parts, and housings exposed to extreme conditions
- Industrial Manufacturing: Heavy-duty gears, bearings, and structural components subjected to high mechanical loads and harsh chemicals
- Aerospace: Critical components requiring high strength, lightweight properties, and high thermal resistance
- Electronics: Enclosures and housings requiring superior strength, heat resistance, and dimensional stability
- Consumer Goods: Durable parts for tools, appliances, and machinery exposed to high mechanical stress and chemicals

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.
