POLYTETRAFLUOROETHYLENE (PTFE TEFLON)

PTFE Virgin Grade has the lowest coefficient of all  materials and is ideal in applications where lubricants are not desirable as KEYLON® PTFE functions without any lubricants. PTFE has the widest working temperature range of all plastics, from -260°C to 260°C. PTFE is excellent for use in cryogenic applications as shows no embrittlement. KEYLON® PTFE has very good sealing properties. PTFE is not flammable unless in 94% oxygen environment. KEYLON® PTFE is an excellent insulating material. KEYLON® PTFE is not ideal in high wear abrasive applications or in high loading applications. Here filled PTFE is used to improve resistance to load and wear.
