PPA
PRODUCT DETAILS
PPA – High-Temperature, High-Strength Polyphthalamide for Advanced Engineering Applications
Our PPA (Polyphthalamide) is a high-performance, semi-aromatic nylon engineered for exceptional heat resistance, mechanical strength, dimensional stability, and chemical durability. Designed for demanding environments where standard PA6/PA66 cannot perform, PPA is widely used in automotive, electrical, and industrial precision components.
Key Features
-
Outstanding heat resistance
With a high melting point and excellent thermal stability, PPA performs reliably in continuous high-temperature environments. -
Superior mechanical strength & stiffness
Provides high tensile strength and rigidity, even under thermal load. -
Low moisture absorption
Ensures exceptional dimensional stability compared with traditional nylons. -
Chemical & fuel resistance
Withstands automotive fluids, oils, coolants, and harsh industrial chemicals. -
Excellent creep resistance
Ideal for load-bearing parts under long-term mechanical stress. -
Stable electrical insulation
Suitable for high-voltage and high-temperature electrical components. -
Enhanced wear & friction properties（reinforced grades）
Optional glass fiber/mineral-filled versions provide even greater toughness and stability.
