application:
farida bipb is a widely used curing agent for plastics and rubbers, such as cpe, epdm, eva, silicone rubber, nbr and fluorubber. compared with dcp, bipb is more efficient at less dosage and much lower odor in the processing and final products. in the case of equal crosslinking effectiveness, the additional content of bipb is just 2/3 of that of dcp. which means it is, especially, suitable for insulation crosslinking of cord and eva foam products. also can used as degradation agent for pp.

package and storage:
inner package: n.w. 5kg/pe bag; outer package: n.w. 20kg/carton, i.e. 4bags/carton.
farida bipb should be stored at room temperature. keep away from direct sunlight, heating, violent shaking, strong acids and reductive agents during transportation or storage.
