> Products > PTFE1. PTFE (PolyTetraFluoroEthylene)
| Characteristics |
|---|
|
ㆍ A crystalline resin with a high degree of shrinkage is greater injection, extrusion processing is possible, a transparent molded article can not make. ㆍ Liquidity is good and milky and translucent. ㆍ For nearly all chemicals and solvents and is stable. ㆍ Cutting and mechanical processing is relatively easy. ㆍ Can be used continuously at high temperatures (continuous use temperature of 260 ℃) ㆍ A low dielectric constant and loss factor to have a wide range of frequency, temperature stable and excellent in electrical characteristics. ㆍ Non-absorbent, low friction resistance. (Absorption very close to near ‘0’ ) And, ductility, weather resistance, non-tackiness is excellent. |
| Applications |
|
ㆍ Machine parts in semiconductor produce line: valves , cock, joint, filter, tube, lining and gaskets ㆍ General machine parts. Auto parts as bearings ㆍ Electric insulator: tape, film, wire clothing, terminal ㆍ Etc: Additives, Coating in kitchen applications. |
