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.
