PPA — Polyphthalamide High Performance Polyamide Resin

PPA — Polyphthalamide High Performance Polyamide Resin

PPA (Polyphthalamide) is a semi-aromatic high-performance polyamide offering superior heat resistance, low moisture absorption, and excellent mechanical properties. It bridges the gap between standard nylons and ultra-high-performance polymers.

Key Properties

• High heat deflection temperature (HDT up to 290°C reinforced)
• Low moisture absorption compared to PA6/PA66
• Excellent dimensional stability
• Good chemical resistance to automotive fluids

Typical Applications

• Automotive under-hood components
• LED lighting reflectors and housings
• SMT-compatible electronic connectors
• High-temperature industrial parts
