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 4200 Series Thermoplastic Polyimide Compounds
Advantages
High heat resistance
High strength and stiffness
Chemical resistance
Wear resistance
Limitations
Cost
High processing temperatures
Post annealing needed if operating temperatures above Tg
Most RTP 4200 Series products are based on a semi-crystalline thermoplastic polyimide (TPI). However, TPI is also available as an amorphous polymer. In either case, it has excellent properties at elevated temperatures.
TPI is the most heat resistant thermoplastic available and has excellent physical properties, along with chemical and wear resistance. TPI is also inherently flame retardant.
