Product Application of OBSH CAS#80-51-3

Foaming agent for rubber and plastic industry. Organic sulfonyl hydrazide foaming agent is widely used and is known as a universal foaming agent.

It can be used in polyvinyl chloride, polyethylene, polypropylene and ABS resin, etc. It can also be used as a blend of rubber and synthetic resin and as a foaming agent for various synthetic rubbers.

Applicable products include wallpaper, carpets, communication cables, artificial leather and various packaging materials. Its cell structure is fine and uniform, and it is especially suitable for manufacturing various foam plastics such as polyethylene foamed wire and cable insulation materials and microporous PVC paste foam. Used together with sodium bicarbonate to lower the decomposition temperature. When used in chloroprene rubber, it also has the effect of promoting vulcanization.
