Abstract:
1. A method for production of a highly filled elastomeric compound comprising: forming a highly filled elastomeric compound from an elastomeric resin wherein a filler comprises about 110% to about 500% by weight of the elastomeric resin; and adding dry microsilica to the highly filled elastomeric compound in an amount of 255% to 400% by weight of elastomeric resin as a modifier to improve processability, wherein the microsilica is particulate amorphous SiO wherein the elastomeric resin comprises a polymer selected from the group consisting of natural rubber (NR), ethylene-propylene-diene rubber (EPM and EPDM), styrene-butadiene rubber (SBR), acrylonitrile-butadiene rubber (NBR), polychloroprene rubber (PCP), acrylate rubber, NBR blended with polyvinyl chloride, ethylene vinyl acetate copolymer and blends thereof.
