摘要(Abstract):

膨胀聚四氟乙烯密封胶带是用聚四氟乙烯制成的低密度密封材料。它具有柔性、可压缩性、高抗拉强度及化学性稳定等性能。这种密封材料的独特性能,使它适合于各种不规则的表面,用适当的螺栓力便被压成一个薄垫片。完全不受通常化学物料的影响,长期使用不变质,适用于温度范围为-450°F~+600°F(-268°~+315°C)的场合,且在使用中它不会在法兰上留下残渣,也不会污染物料。
Joint sealant gasket of expanded PTFE made of pure PTFE is a continuous low density cord. It is flexible, compressible exhibits high tensile strength, and is ehernically inert. This unique combination of properties permits it to conform easily to irregular surfaces and compress to a thin gasket while using moderate bolting force. It is completely unaffected by all common chemicals, does not deteriorate with age, may be used over the temperature range of -450°F to +600°F (-268℃ to +315℃), will not leave a residue on the flanges, and will not contaminate flow products.
