PTFE coated release fabrics and adhesive tapes for vacuum bagging, autoclave layup and prepreg moulding in aerospace, sports and wind composite production.
Composite manufacturing — from carbon fibre prepreg to wet layup — relies on flawless release surfaces. Resin systems based on epoxy, BMI and polyester are highly aggressive and bond strongly to almost any surface they contact. The release fabric or tape between the part and the tooling determines surface finish, demoulding integrity and tool life.
Shree Tefcon supplies the composites sector with PTFE coated fiberglass release fabrics, peel-ply alternatives and high-temperature PTFE adhesive tapes engineered for repeated autoclave and oven cures. Our materials are used by aerospace tier suppliers, wind blade manufacturers, sports equipment OEMs and marine composite fabricators.
Autoclave and oven cures at 180°C+ degrade lesser materials quickly — release fabrics must survive dozens to hundreds of cycles.
Pin-holes or weave gaps cause vacuum loss and porosity in finished parts.
Aerospace structural and visual parts demand mirror-smooth release with zero fabric imprint.
Different chemistry (epoxy, polyester, vinyl ester, BMI) requires PTFE coatings that remain inert.
