Release films

Release Films are used in the composite manufacturing process not only to ensure release from breatherand other vacuum bagging products, but also to control the flow of resin.Solid release films are used to completely contain the flow of resin within the laminate, whereas perforated release films offer a controlled bleed of excess resin into the bleeder cloth.

The use of release film will vary based on application, but Airtech as the manufacturer, has engineered a release film that is effective and economical for every application. Airtech offers the widest selection offluoropolymer release filmson the market with A4000 and WL5200 offered from stock up to 120inch(3.05m) wide.

Release Films are available for use at all temperature ranges up to 752°F (400°C).Airtech release films are manufactured in both non-perforated and perforated styles. Review the ‘Available Perforations’ page in Release Films section of the catalog for perforation details.
