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.
