Torlon 4203 Stronger and Tougher than PEEK and Polyimide from cryogenic to 500°F

Torlon 4203 and Torlon 4203L are non-reinforced polyamide-imide. The “L” designates resin designed for injection molded shapes and parts.  Extruded shapes are made from the highest viscosity Torlon 4203 resin resulting in improved toughness, impact strength and fatigue resistance over injection molded parts.  Torlon 4203 is the toughest and most impact resistant of the Torlon grades making it the choice for highly loaded wheels, rollers and balls. It has excellent dielectric properties and is also the best thermal insulator making it suitable for:

Torlon 4203 is ideal for: 

• Valve seats/seals requiring high strength and dimensional stability

• Rollers, wheels and balls

• aerospace electrical components requiring high strength, heat resistance and low flammability

• Thermal insulators and insulators

Torlon 4301 Stronger and Tougher than PEEK and Polyimide from Cryogenic to 500°F

Torlon 4301 is a high modulus polyamide-imide containing graphite and PTFE for improved wear resistance.  It is the general purpose wear grade of Torlon with an excellent balance of strength and impact resistance. It offers 10 times more wear resistance than non-reinforced Torlon 4203 and has a CLTE that approaches that of many metals.

Torlon 4301 is ideal for:  

• Bushings (highly loaded)

• High temperature wear pads

• Thrust washers

Torlon 5030 Stronger and Tougher than PEEK and polyimide from cryogenic to 500°F

Torlon 5030 is a high modulus polyamide-imide containing 30% glass fibers well suited for highly loaded structural parts plus electrical insulators and thermal isolators operating at temperatures above 300°F. It offers a 50% lower CLTE than non-reinforced Torlon 4203 but without the conductivity of carbon fibers. Its CLTE is similar to aluminum. The strength and creep resistance of 5030 is unmatched among high temperature polymers above 300°F and its modulus second only to Torlon 7130 over its operating range.

Torlon 5030 is ideal for:

• High temperature thermal/electrical insulators

• Test sockets for IC’s

• Fasteners

• Activation balls and valve seats
