CELOGEN® 765A is an activated azodicarbonamide chemical foaming agent for rubber and thermoplastic formulations.
CelChem LLC CELOGEN® 765A is an activated azodicarbonamide foaming agent for various rubber and thermoplastic formulations. As a chemical foaming agent, it provides non-discoloring benefits for rubber and thermoplastic systems, requiring a reduction in overall density. It is similar to CELOGEN® 754A but with a lower decomposition temperature. CELOGEN® 765A contains a very effective activation system; adding potent activators such as zinc oxide, zinc stearate, treated urea, or ACTICELL® U is unnecessary unless lowering the decomposition temperature is desired.
