PRO-VAC GENERAL PURPOSE VACUUM BAG FILM – PRO-VAC General Purpose Vacuum Bag Film is excellent for use with polyester and epoxy infusion systems, and in the production of large, complex parts. It’s a tough, puncture resistant co-extrusion of polyolefin and nylon based resins. Due to its structure, this product is less sensitive to deviations in humidity than other popular vacuum bag films. This film is designed for the low-temperature composite processing. The film’s range is appropriate for use with composites from small-scale automotive parts to large resin infusion of wind blades and yachts. Use in the production of epoxy and polyester/vinylester resin-infused components. Green, low-temperature, co-extruded, PO/PA/PO vacuum film. Limited sensitivity to low humidity levels which are often problematic to predominately nylon based films as lack of moisture can reduce flexibility. PRO-VAC 150 ensures consistent performance year-round in all workshop environments. Maximum use temperature of 120°C (248°F). Product is sold by the roll.
