Abstract:

Tape comprising a polymer composition, said polymer composition comprising at least one fluoropolymer and a modifier consisting of at least one aromatic polyimide chosen from aromatic polyamide-imides and aromatic polyesterimides, and, optionally in addition, at least one aromatic polyimide chosen from aromatic polyimides other than aromatic polyamide-imides and aromatic polyesterimides, said modifier being comprised in the polymer composition in an amount of up to 75 wt. % (based on the total weight of the polymer composition). Article comprising said tape. Processes especially well-adapted for manufacturing said tape. Use of the above modifier as an additive of a polymer composition comprising a fluoropolymer, to increase the abrasion resistance either of a tape comprising said polymer composition, or of an article comprising an outermost layer which covers at least partially the article, said outer most layer comprising a tape comprising said polymer composition.
