TO STUDY THE BLENDS OF EPDM RUBBER WITH LDPE

Several formulations containing EPDM and LDPE were prepared. EPDM was blended with LDPE in different weight ratios of LDPE/EPDM (40/60, 30/70, 20/80, 10/90). These compounds were mixed at 150oC in open mill for 10 min at a speed of 19.03 rpm and then mixed with phenolic resin. Here, phenolic resin grade SP-1068 used which work as a tackifier resin. The mechanical, thermal, morphological, dynamical and electrical properties of polymeric insulators will be tested and reported in thesis. In future, the result of mechanical measurement shows that mechanical properties such as tensile strength, modulus and elongation-at-break of blends can be enhanced with increase in LDPE in the formulation. Also tests will be conducted to study various properties (mechanical, surface, electrical) under accelerated ageing condition. Because the life time of these compounds are generally too long to wait for a verdict on their behavior in use.
