application:
Foaming agent OBSH When this product is used alone, it can produce a fine, high-quality, and uniform pore structure, and the foamed product is odorless, tasteless, non-polluting, and non-discoloring. It is especially suitable for odorless and light-colored foaming products. Foaming agent OBSH can be applied to natural rubber and various synthetic rubbers (such as: EPDM, SBR, CR, FKM, IIR, NBR and thermoplastic products (such as PVC, PE, PS, ABS), and can also be used in rubber-resin mixtures The foaming agent OBSH has good insulation and can be used in the manufacture of wires and cables.
Blowing agent OBSH can, under certain circumstances, act as both a blowing agent and a crosslinking agent in the curing mechanism.
Suitable for all foam or foam rubber products

Packaging and storage:
