Product features

An oil-soluble azo initiator, white crystal (slightly yellowish), without cyano group, decomposition products are non-toxic, more widely used.

Product Application

Construction industry textile industry printing and dyeing industry paint industry transportation industry packaging industry chemical industry

Product use

Used as a free radical initiator for polymers such as the initiation of polymer polyols POP. As an azo polymer initiator, dimethyl azobisisobutyrate has its unique


Moderate initiation activity and easy control of polymerization reaction.

Several major domestic POP manufacturers have successively switched to dimethyl azobisisobutyrate as the initiator. The resulting products have low viscosity, less residual monomers, are relatively stable during storage and transportation, do not delaminate, and have high product conversion rates. It also increased by about 1%, effectively reducing the overall cost.
