PTFE RELEASE FILM

PTFE Release Film

PTFE (polytetrafluoroethylene) release film is a non-porous, chemically inert release film used in composite laminating and vacuum infusion processes. Its ultra-low surface energy means it releases cleanly from virtually any resin system — epoxy, polyester, or vinyl ester — leaving a smooth, non-tacky surface ready for bonding or painting.

Key Features

• Non-porous — produces a smooth, resin-rich surface finish
• Zero resin bleed-through — ideal where a controlled surface is required
• Compatible with epoxy, polyester, and vinyl ester resin systems
• Chemically inert and heat-stable up to typical cure temperatures
• Available in 1000mm roll and 5m cut lengths

Typical Applications

• Sandwich panel manufacture requiring a smooth inner skin
• Vacuum bagging over prepreg or wet lay-up laminates
• Tool-side release in closed mould processes
• Any application where peel ply texture is not desired
