n [4,4’-oxybis(benzenesulfonylhydrazide), OBSH] A blowing agent, a white crystalline solid that melts and begins to decompose near 105°C. It produces a white unicellular foam when incorporated in PVC plastisol but has a strong residual odor that does not evolve when it is used in rubbers. It is also used in epoxy and phenolic foams and serves as a cross-linking agent in rubber compositions and a rubber/resin blends. Open image in new window
