PTFE Bronze filled provides enhanced mechanical properties, dimensional stability and thermal conductivity compared to standard grades of PTFE. The polymer offers a broad operating temperature and low cold creep, but provides the weakest resistance to chemicals of any of the PTFE grades available due to the filler. It is comprised of 60% Virgin PTFE and 40% bronze powder, which helps to create a material that provides resistance to wear under high compressive loads and dissipate static and heat build-up when in application.
High performance shaft bearings, slide plates and gaskets. Bronze PTFE is also commonly manufactured into bearing, piston and wear rings.
Characteristics:
- Temperature: -200°C up to +260°C.
- Excellent resistance to low and high temperatures.
- Inferior chemical resistance to other grades of PTFE (it can be attacked by acids and alkali metals).
- Provides enhanced mechanical properties and dimensional stability.
- Helps to dissipate static build up (volume resistivity of 106 Ohms)
- Very good sliding and non-stick properties.
- Very low coefficient of friction.
- Provides good thermal conductivity.
