PTFE Thread Seal Tape
【 特 征 Features】
|
聚四氟乙烯具有很多优良的性能。诸如很低的摩擦系数、不粘的表面特性、宽广的使用温度范围-180°C - +260°C、优良的耐老化及耐化学腐蚀性能等。
膨体聚四氟乙烯生料采用100%聚四氟乙烯作原料,它具有微细长纤维和节组成的网状膨体结构。膨体聚四氟乙烯生料带并具有韧性好、纵向强度高、横向易于变形的特点。它是盘根及螺纹上密封的理想材料。但它不能在与高浓度氧气或液气相接触的场合使用。
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 debbbbability 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.
