Popular Toughening Agent CPE for PVC Products

Processing modifier CPEChlorinated polyethylene (CPE) as the saturated polymer material, appearance is white powder, non-toxic tasteless, has excellent weathering resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and shading performance.Chlorinated polyethylene CPE135A is retrofit plastic, is made of special polyethylene under the effect of chlorine atom was prepared by chlorination, it has excellent comprehensive physical properties, such as low temperature toughness; Have higher tensile strength; And very close to PVC solubility parameters, good affinity; Give the correct processing conditions, the network structure is formed within the hard PVC products, giving products excellent, low temperature toughness and impact strength.
