Dahlar® RB 500
Dahlar® Release Bag 500 is a self releasing multi-layer bagging film for direct contact with pre-preg for fabrication of hollow parts. Dahlar® Release Bag 500 exhibits superior strength, temperature resistance and vacuum integrity of Airtech's multi-layer film technology. Dahlar® Release Bag 500 exhibits excellent release of epoxy and polyester resins. Maximum use temperature is 450° F (232° C) with a tensile strength of 8702 psi.
Dahlar® Release Bag 500 is also available in gusseted folding (LFT-G).
Thanks to the gusset folding, the 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.
