The pure expanded PTFE has a high malleability allowing flange sealing even damaged, while its low relaxation under load ensures high efficiency assembly. By requiring low torque, the expanded Teflon is recommended in fragile flanges coated glass or plastic. Its purpose is to seal against aggressive agents and food applications as this material is according to the FDA. We can also source expanded PTFE (e-PTFE) tape in various formats.
Our expanded PTFE tape with adhesive stripe for flanges is a sealant, manufactured from 100% pure expanded PTFE. It is typically produced as a tape and comprises all the exceptional operation parameters of PTFE plus the additional features acquired in the process of expansion. To facilitate the fitting, it is provided with a one-sided adhesive backing strip with protective layer made from special paper, which is removed before fitting. Due to its excellent flexibility and ductility it follows very easily the shape of the sealed surface, and the adhesive strip enables a very quick installation. Apart from the flange sealing our expanded PTFE tape may be successfully used in every other case of static sealing, provided that the working parameters fall into the range PTFE’s values.
