Abstract: The paper studies the impact of BIPB vulcanization system on the physical properties of chlorinated polyethylene rubber(CM),optimizes the best ratio of BIPB-CAMV dosage.Orthogonal design test method is used,and the experimental results show that using BIPB to instead of DCP vulcanized rubber is entirely feasible whether it is in tensile strength,elongation,hardness,or in tear strength,compression deformation and other properties and processing technology.Because BIPB contains two peroxy bonds,the active oxygen content is high,and the oxygen dosage of BIPB is less one third than DCP.
