Polytetrafluoroethylene or PTFE is a versatile fluoropolymer. It is suitable for a wide range of applications in industries as diverse as aerospace, the food and drink industry, pharmaceuticals and telecoms.
Teflon Materials.
OZ PTFE (POLYTETRAFLUORIETHYLENE)
100% pure PTFE, white with hardness 55 D, is resistant to almost all chemicals apart from fluorine, molten alkali metals and halogens. It also has very good sliding properties. Due to its low elasticity, PTFE virgin is not suitable with high mechanical loads. PTFE has a poor thermal conductivity, a high expansion coefficient and a low loading capacity as bearing material. It also has low resistance to abrasive wear.
Features
- Good mechanical resistance if reinforced with glass, carbon or bronze
- Excellent chemical resistance to almost all commercial fluids & chemicals
- Highly stable electrical insulating properties
- Has weather resistant properties
- Excellent resistance to extreme heat & cold
- Self-lubricating properties
- Temperature range: -200 to 260°C
- Grades: virgin, carbon filled, glass filled, bronze or PPS filled
OZ TMCF (CARBON FIBER FILLED PTFE)
This material is available in a mixture of PTFE virgin, carbon fillers and additives. Its colour is black with a hardness of 60 shore D. Oz TMCF has good dry running properties and is used for seals in compressors or lip seals. Exceptional wear life over conventional carbon grades.
Examples of applications: Seal rings, piston rings and compressor rings
Features
- Used in dynamic applications at high speed
- Good loading properties
- Suitable for higher load gasket applications
- Exceptional wear life over conventional carbon grades
- Examples of applications: Seal rings, piston rings and compressor rings
OZ TFG (25% GLASS FILLED PTFE)
TFG 25% Glass contains of 25% clean milled fibres and 75% PTFE virgin and is available in white with a hardness of 60 shore D. This material offers a higher stiffness and better wear properties than PTFE virgin. It is not useable for soft metal counterparts and has a limited usage in hot water.
Features
- Improved creep resistance over all temperature ranges
- Improved wear behavior
- Exceptional resistance to water
- 25% glass must be avoided with the use of strong alkalis and hydraulic acid
- Ideal for high load bearing applications
