Azodicarbonamide foaming agent for producing many types of polymeric and elastomeric closed-cell foams. Similar to CELOGEN® AZ1901 but with a larger particle size.
CELOGENĀ® AZ2500 is a chemical foaming agent that produces a fine, uniform, closed cell structure. It has a relatively high decomposition temperature and large particle size.
CELOGENĀ® AZ2500 can be catalyzed by a variety of chemicals. Strong activators like zinc oxide, zinc stearate, and ACTICELLĀ® U; moderate activators like barium stearate, calcium stearate, citric acid, and triethanolamine; or weak activators like adipic acid, benzoic acid, salicylic acid, and calcium oxide.
