These compounds are common formulations which provide comparative information on the wear properties of this resin and various combinations of additives.
Instead of off-the-shelf solutions, RTP Company routinely develops specialty compounds with a precise combination of properties such as conductivity, flame retardance, structural reinforcement, color, and wear resistance to meet your exact application requirements.

RTP 4000 Series Polyphthalamide Compounds
Advantages
Heat resistance
Chemical resistance
Relatively low moisture absorption
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.
