PPA — Polyphthalamide
PPA is a semi-aromatic high-performance polyamide with high temperature resistance, high stiffness and excellent chemical resistance.
What is PPA?
PPA is a semi-aromatic high-performance polyamide with high temperature resistance, high stiffness and excellent chemical resistance.
Typical properties
| Density | ~1.15–1.25 g/cm³ |
| Tensile strength | ~80–120 MPa |
| Heat deflection | high |
| Moisture absorption | lower than standard polyamides |
Typical applications
Automotive componentsElectronicsConnectorsPump partsHigh-temperature components
Industries
AutomotiveE-mobilityElectrical industryMechanical engineeringIndustrial electronics
Processing
Injection moulding at high processing temperatures. Drying is critical — PPA is sensitive to residual moisture.
