PPA-CF5 | 5% Carbon Fiber Reinforced Polyphthalamide
PPA-CF5 is a high performance, semi-crystalline engineering thermoplastic reinforced with 5% short carbon fiber, offering enhanced stiffness, dimensional stability, and thermal resistance compared to unfilled PPA. Designed for use in automotive, electronics, and industrial components, PPA-CF5 delivers lightweight mechanical performance with improved warpage control, creep resistance, and surface finish, all while retaining PPA’s inherent chemical and thermal durability.
PPA-CF5 provides a balanced solution for cost sensitive applications where moderate reinforcement, high precision, and good flowability are essential.
Core Performance Highlights

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.
