PPA-CF40 | 40% Carbon Fiber Reinforced Polyphthalamide
PPA-CF40 is an ultra high-performance, semi crystalline engineering thermoplastic reinforced with 40% short carbon fiber, engineered for maximum strength, rigidity, and dimensional stability in extreme mechanical, thermal, and chemical environments. With its very high carbon fiber content, PPA-CF40 offers metal like mechanical properties combined with the inherent chemical and heat resistance of polyphthalamide.
Compared to lower carbon fiber grades such as PPA-CF20 and PPA-CF30, this material exhibits significantly enhanced stiffness, creep resistance, and thermal dimensional control, making it ideal for structural parts subjected to high loads, elevated temperatures, or chemical exposure over long service life.

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.
