Profile: Tygavac Advanced Materials Ltd manufactures vacuum bag materials used in the molding process for manufacturing advanced composite components. Our products include bagging films, vacuum bag sealant tapes, released & bleed-out films, PS tapes, vacuum fittings & accessories and resin infusion products. Our bagging films are thin flexible membranes for the vacuum bagging application. Once sealed onto the tool edge a vacuum is drawn under the bag film, which creates a uniform compressive force over the surface of the structure under the vacuum bag. We stock a comprehensive range of release fabrics and peel plies. These materials are porous, woven fabrics which are used to impart a textured surface to the molded component to improve adhesion in subsequent secondary bonding and painting. They can be used between the component and the tool surface or as a separating layer between the component and breather fabric. In the latter case they allow the vacuum to bleed air and volatiles out of the laminate to prevent voids.
