APPLICATION:
OBSH-75 is maked by ultra-fine and homogeneous OBSH, together with rubber carrier, and it's more stable and safer than OBSH powder. OBSH-75 is using for the products which are orderless, tasteless, no pollution, no decoloration, fine and cellular structure products. As a blowing agent, OBSH-75 is used in all foaming products with character of foaming evenly, good physical property and stable. It can easily disperse in the rubber products and combined with other blowing agent in the compounds. OBSH-75 is non-toxic, with no pungent odour and it is suitable for automatic weighing to keep accuracy.
