聚四氟乙烯具有很多優(yōu)良的性能。諸如很低的摩擦系數(shù)、不粘的表面特性、寬廣的使用溫度范圍-180°C - +260°C、優(yōu)良的耐老化及耐化學(xué)腐蝕性能等。
膨體聚四氟乙烯生料采用100%聚四氟乙烯作原料，它具有微細(xì)長纖維和節(jié)組成的網(wǎng)狀膨體結(jié)構(gòu)。膨體聚四氟乙烯生料帶并具有韌性好、縱向強度高、橫向易于變形的特點。它是盤根及螺紋上密封的理想材料。但它不能在與高濃度氧氣或液氣相接觸的場合使用。
The remarkable properties of polytetrafluoroethylence(PTFE) are well known, Notably its low coefficent of friction, non stick surface characteristic , wide working temperature range from -180°C - +260°C. Excellet weathering resistance and corrosion resistance.
PTFE thread seal tape is made from pure PTFE. It has an expanded network composed of superfine fibers and joints . The combination of flexbility high longitudinal strength, and easy deformability in the transverse direction, makes it very suitable for packing and thread sealing applications. But it is not suitable for using in certain critical application , for example when contact with high concentration of gaseous oxygen or liquid oxygen involved.
