• Cost
• Strength or physical properties

Limitations
• Not inherently flame retardant
• Requires good drying equipment
• High processing temperature

Polyphthalamide (PPA) is a semi-crystalline, aromatic polyamide. Compared to nylon 6/6, it is stronger, stiffer, less sensitive to moisture, and has higher thermal capabilities. It has significant chemical fatigue and creep resistance.

PPA resins are suitable for a wide range of applications because of their outstanding physical, thermal and electrical properties. They can resist infrared soldering environments, unlike many other resins.
