PFA-WF Welding Film VERSIV

PFA-WF Welding Film is a fluoropolymer film made from perfluoroalkoxy (PFA) resin. This is a cost-effective solution for use in high-temperature applications that do not require high aesthetic or electrical standards – like hot melt adhesive (welding tape).

PFA-WF Welding Film

Used as hot melt adhesive (welding tape) for bonding PTFE-coated fabrics and fluoropolymers together to form architectural structures, belts and fabricated items, PFA-WF Welding Film offers excellent chemical and thermal resistance – at a lower price point than PFA type PG.

Product Details

In applications where electrical and optical properties are not the main considerations, PFA-WF Welding Film provides the same thermal and chemical resistance as PFA type PG, but at a more affordable price. Bondable under pressure and heat to PTFE-coated fabrics and fluoropolymers, compared to using traditional adhesive chemistry it provides the chemical and thermal resistance of a full fluoropolymer construction. Often used to form seams on belts that operate in elevated temperature environments (for example, for those used in ovens), it is our recommended welding tape for these types of PTFE coated fabric belt applications.
