扩大的聚四氟乙烯共同密封胶和自粘踢踏

Expanded PTFE Joint Sealant tape is a 100% expanded PTFE gasket material and combined with a self-adhesive strip for easy application. It can be used as a jointing on all types of flanges and can be used with almost all fluids for its excellent corrosion resistance, high pressure resistance, convenient in using, soft and stretched structure, Sticked onto sealing face(it has glue on one face) with one piece of belt, two ends of which are crossed together that would be formed a sealing gasket. So it is an ideal sealing material for enamel, glass, rough and special shaped sealing surface.
