Abstract:A series of chlorinated polyethylene rubber (CM)/ethylene vinyl acetate (EVA) blends were prepared at different blending ratio. The blends were foamed by compression molding and azodicarbonamide (AZDC) was used as chemical blowing agent. Cure characteristics were researched first, and then the morphology and physical properties were investigated. It was found that neat CM foams presented a series of problems such as low hardness and high shrinkage ratio. To solve the above problems, some EVA was added into CM matrix. And the results indicated that these aforementioned defects were improved after the addition of EVA component. Tensile strength increased first and then fell, and morphology properties of CM/EVA blends were also investigated. POLYM. ENG. SCI., 2012. (C) 2011 Society of Plastics Engineers
