Release film, also known as Peel Ply or PTFE is a tough, finely woven fiberglass that has been treated with a release agent. It is used as a barrier to separate the bleeder/ breather and vacuum bag from the composite laminate during vacuum bagging.The peel ply allows excess epoxy and resin to bleed through and is then removed from the cured composite laminate along with the Release film. Peel ply removes easily and leaves a smooth textured surface ready for bonding or finishing.
We Do Not recommended for post-cure temperatures over 120 F (49 C). We stock large volumes of all our vacuum bagging supplies and vacuum infusion supplies. They are available in lengths ranging from one linear yard to full rolls.
