Dahlar®Release Bag 520 is a self releasing multi-layer bagging film for direct contact with pre-pregfor fabrication of hollow parts.

Dahlar®Release Bag 520 exhibits superior strength, temperature resistance up to 220 °C and vacuum integrity of Airtech'smulti-layer film technology. Dahlar®Release Bag 520 exhibits excellent release of epoxy and polyester resins.

Dahlar®Release Bag 520 is also available in gusseted folding (LFT-G). Thanks to the gusset folding, the Dahlar®Release Bag 520 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 arevariations 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.Airtech Europe a division of Airtech Advanced Materials Group, is proud to announce the introduction of Dahlar®Release Bag 520 small bore tubing, developed for the manufacture of high performance hollow parts.
