Compoflex® SB 250

Compoflex® SB 250 is a peel ply, release film and breather, used to control flow rate and release consumables from a composite laminate. Compoflex® SB 250 generates a very rough and textured surface ideal for secondary bonding or painting of a composite laminate.

Compoflex® SB 250 may reduce or eliminate the need for sanding or abrading. Best results with epoxy resin, but we always recommend testing. Release film perforation style: low to medium bleed characteristics.

Compoflex® SB 250 is a medium weight breather (150g / 5 oz) ideal for low pressure cures and can be used as bleeder at any pressure. Works well with polyester, vinylester, epoxy, phenolic and other types of resin.
