CELOGEN® AZ-1901 is an azodicarbonamide foaming agent for producing many types of polymeric and elastomeric closed-cell foams. It is similar to CELOGEN® AZ-9370 but with a larger particle size.
CELOGEN® AZ-1901 is a chemical foaming agent that produces a fine, uniform, closed-cell structure. It has a relatively high decomposition temperature and small particle size. CELOGEN® AZ-1901 can be catalyzed by a variety of chemicals: strong activators, such as zinc oxide, zinc stearate, and ACTICELL® U; moderate activators, such as barium stearate, calcium stearate, citric acid, and triethanolamine; and weak activators, such as adipic acid, benzoic acid, salicylic acid, and calcium oxide.
