Abstract
The effects of three types of carbon blacks, namely, semireinforcing furnace, high abrasion furnace and intermediate super abrasion furnace on the physical properties of poly(ethylene-co-vinyl acetate) have been studied. The properties studied include cure characteristics, mechanical properties, solvent transport behaviour, dielectric properties and the thermal characteristics. The properties were evaluated in terms of the particle size and amount of the fillers used. The mechanical properties of the matrix such as tensile strength, abrasion resistance and hardness were observed to be increasing with filler incorporation. Solvent resistance of the composite has also been observed to be increasing with filler incorporation. The dielectric constant and thermal behaviour of the composite has been studied and explained in terms of the particle size of the filler used.
