【 摘 要 】

The interface between either Micronised Rubber Powder (MRP) or Crumb Rubber Powder (CRP) fillers in eitherNatural Rubber (NR) or Butadiene Rubber (BR) matrices has been studied using Transmission Electron Microscopy (TEM)‘network visualisation’. The convoluted structure of CRP provides better interfacial adhesion than MRP. The weak interfacebetween the MRP networks and the rubber matrix was confirmed by the lower physical bonding. The crescent tear strengthtest was able to characterise the possible weak interaction of MRP in unfilled NR or NR/BR blend matrix. The Akron testwas used for carbon black-filled matrix.
