Description

Dahlar® Release Bag 500 is a self releasing multi-layer bagging film for direct contact with prepreg for fabrication of hollow parts. It exhibits superior strength, temperature resistance and vacuum integrity of Airtech's multi-layer film technology. This product exhibits excellent release of epoxy and polyester resins.

This product is also available in gusseted tubing (GT). Thanks to the gusset folding, Dahlar® Release Bag 500 is easier to position accurately in hollow parts. Upon application of pressure the bag will easily expand to fit to the shape of the part which is very useful in applications where there are variations in the part diameter. This development ensures even application of internal pressure in cases of small diameter parts, where the insertion of a standard lay flat tube bagging film can be problematic.

Benefits

• Multi-layer construction combines release and vacuum performance in a single material.
• Easier to position accurately in hollow section, reduces cycle time, and improves quality.
• Easier to remove after cure reducing cycle time.
