Torlon 7130
Torlon 7130 is a 30% carbon reinforced grade that provides the highest stiffness and lowest
coefficient of thermal expansion for any engineered plastic. The carbon makes this grade
electronically and thermally conductive, and it can maintain its strength in temperatures reaching
500°F. Other properties include high load bearing capabilities and excellent heat dissipation. Torlon
7130 is used to manufacture parts in the automotive, aerospace, oil & gas, consumer goods,
industrial, and construction industries.
Applications of Torlon 7130
- Landing gear bushings
- Wear strips
- Precision dowel pin guides
- Long wear chain bushings
- Pump vanes
- Impellers
- Wear rings
- Shrouds
- Pistons
- Housings
