Modified PPA Plastic Pellets

Dimensionally stable and conductive PPA CF20 Plastic

Carbon Fiber Reinforced PPA: CF20 PPA
Full name / composition: PPA + 20% Carbon Fiber.
Nature: Short-cut carbon fibers (20%) are incorporated into the PPA matrix. This represents a higher-end reinforcement solution.

Differences from GF20 PPA:
Higher rigidity and strength: Carbon fiber has a much higher modulus and strength than glass fiber.

Excellent fatigue resistance.
Extremely low coefficient of linear thermal expansion: Dimensions change minimally with temperature, suitable for precision components.
Provides conductivity/anti-static properties: Carbon fibers can form conductive networks, suitable for anti-static or electromagnetic shielding applications.
Lighter weight: Carbon fiber density is lower than glass fiber.
Higher cost: Raw materials and mold wear costs are significantly higher than GF materials.

Main Applications:
Situations requiring extreme lightweight and rigidity: drone structural components, robotic arms, high-end sports equipment parts.
Electronic enclosures or brackets requiring electromagnetic shielding.
Precision optical instrument brackets and barrels (taking advantage of low thermal expansion).
High-performance automotive components (e.g., F1 racing parts).

PREV：Reduced friction and enhanced wear resistance PPA PTFE Plastic
NEXT：Heat-resistant PPA GF30 Plastic
