Release Fabric, also known as peel ply, is a tough, finely woven nylon fabric treated with a release agent. It is used to separate the absorber breather and vacuum bag from the laminate in vacuum bagging operations. It's also used in hand lay-up applications to allow more squeegee pressure and to protect the lay-up from contamination.

Excess epoxy bleeds through and is peeled from the cured laminate along with the peel ply. Peels easily and leaves a smooth textured surface ready for bonding or finishing. Not recommended for post-cure temperatures over 120 F (49 C).

Peel ply comes 60 inches wide in a 9" folded around cardboard, 2 yard folded bag, or a 10 yard roll.  The 2 yard bag comes pre folded and can not be rolled.  Peel ply is not reusable.
