Compoflex® 250
Compoflex® 250 is a peel ply, release film and breather, used to control flow rate and release consumables from a composite laminate.
Compoflex® 250 generates a very smooth surface ideal for painting of the composite laminate. For secondary bonding we recommend Compoflex® SB 250. Release film perforation style: Medium bleed characteristics.
Compoflex® 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.

Notes
Working temperature
Recommended max. working temperature is 144°C (293°F). The melting point for polypropylene is 165°C (329°F). However, it is possible to use Compoflex® at 200°C (392°F) due to the fact that Compoflex® performs before the temperature exceeds the melting point. After cooling, the material becomes stable again, and peeling is just as easy as normal. We recommend conducting a test on a small part first.
