Abstract

PURPOSE: To obtain a sealing tape having improved handling properties and reliability, by stretching not sintered polytetrafluoroethylene film to form small pores in it, and by impregnating the inside of the film with fluid adhesive mass.
CONSTITUTION: A not sintered polytetrafluoroethylene film is stretched, for example, to 10W300 %, and many small pores having an average pore diameter of 0.01W10μ are formed in the film. The small pores and one side of the film are impregnated with fluid adhesive mass obtained by dissolving a blend of synthetic rubber, e.g., butyl rubber, polyisobutylene, and a tackifier, e.g., terpene resin, in a solvent. After the solvent is dried, a releaser consisting of dimethylsiloxane as a base is applied to the back of the film and dried to give the desired tape.
USE: Winding for joint parts, e.g., screw joint of fluid pipeline.
