Torlon 4203
Torlon 4203 is an unreinforced, lubricated, and pigmented grade that has the best impact resistance of any type of Torlon. It also features outstanding wear, creep, and chemical resistance while offering excellent dielectric properties that allow it to support an electrostatic field and dissipate minimal energy in the form of heat. All of these characteristics make Torlon 4203 ideally suited for electrical, aerospace, industrial appliances, and automotive components.
Applications of Torlon 4203
- Highly loaded wheels, rollers, and balls
- Linkage bearings and seal rings
- Valve seats requiring high strength
- Strong, heat and flame resistant electrical components
- Thermal and electrical insulators
- Thrust washers
- Spline liners
