PRODUCTION OF FLUOROPLASTIC PREPREG

摘要

PURPOSE:To produce a fluoroplastic prepreg excellent in perforation processability, outer shape processabllity and reliability when a laminated sheet is produced using the prepreg. CONSTITUTION:A fiber base material is impregnated with a suspension of a fluoroplastic powder with an average particle size of 0.27-0.35mum and the impregnated base material is heated to volatilize moisture and a dispersant and further heated to fuse fluoroplastic to the surface of the base material. This process is repeated two or more times.
