Novel rubber blends made from ultra-fine full-vulcanized powdered rubber (UFPR)

Abstract

Novel ultra-fine full-vulcanized powdered rubber/ethylene-propylene-diene terpolymer (UFPR/EPDM) blends were firstly prepared by compounding ultra-fine full-vulcanized SBR or NBR particles into EPDM matrix. The morphology and mechanical properties of these novel elastomer blends were investigated. Some unexpected and interesting phenomena were observed. A promising method to prepare elastomer blends with excellent performances was proposed.
