ELASTOMER COMPOUNDING COMPOSITIONS

摘要

The viscosity of synthetic and/or natural elastomers is markedly reduced by incorporation of a particulate, finely-divided basic zinc methacrylate-type adjuvant, without adversely affecting the physical properties of the final vulcanizates. This viscosity reduction allows higher levels of fillers and other rubber compounding materials to be used for improved physical properties, while maintaining the level of compound viscosity necessary for processing.
