摘要:
A novel precursor is disclosed. The precursor comprises (a) natural or synthetic rubber; (b) a material selected from the group consisting of thermoplastic vulcanizate (TPV), thermoplastic incorporating microparticles of rubber, and any combination thereof; and (c) a cross-linking agent. In some embodiments, the precursor additionally comprises components such as a cross-linking co-agent, carbon black, fillers. The incorporation of thermoplastic in to the precursor enables the inclusion of carbon black or other fillers without any necessity for addition of plasticizers or process oils.
