摘要

Poly[ethylene(vinyl acetate)] (EVAc) has been blended with polychoroprene (CR) to develop a compound for application in the cable industry.Physical,flame retar-dancy,dielectric,and solvent resistance properties have been investigated for the blends.On air and brine aging,the tensile properties for 50/50 blend remains almost unchanged,though retention in tensile properties is maximum for CR in solvent aging and for EVAc in air aging.50/50 blend shows substantially lower set and hardness compared to EVAc.The limiting oxygen index of 50/50 blend is found to be higher compared to EVAc,which indicates sufficient inflammable capability of 50/50 blend in atmospheric air.A substan-tially lower dielectric constant,conductivity with good physical properties,and inflamma-bility of 50/50 blend suggests its suitability for use as a cable sheathing compound.
