      四氟金属缠绕垫片又称聚四氟乙烯垫片, 国外又叫PTFE垫片或铁氟龙垫片,是由聚四氟乙烯棒、管、板经机械车裁切而成的平垫片或V形垫片,具有耐腐蚀、抗老化和不导电等良好特性。四氟具有耐高压、耐腐蚀、柔软性及回弹性好等优点,PH值在0-14之间。该产品在-100℃~100℃之间,具有良好的机械强度。四氟金属缠绕垫片具有良好的压缩回弹性,适用于温度、压力交变剧烈的密封部位,是管道、阀门、泵、换热器、塔、人孔、手孔等法兰连接处的静密封元件。广泛应用于石化、机械、电力、冶金、造船、医药、原子能和宇航等领域 。
      PTFE metal wound gasket ,also called PTFE gasket or Teflon gasket in foreign countries, is a kind of flat gasket or V shaped gasket made by mechanical cutting of PTFE rods, tubes, plates by mechanical car. It has good characteristics of corrosion-resistant, anti-aging and nonconductive. PTFE has the advantages of high pressure resistance, corrosion resistance, flexibility and good elasticity. PH value of PTFE is between 0-14, and the product have very good mechanical strength at -100℃ to 100 ℃. PTFE metal wound has good compression and resiliance rate, suitable for sealing parts of violent temperature and pressure alternating occasions. It is a the original static sealing elements of pipe, heat exchanger, the groove of the flange connection. The gasket is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace sectors.
