Effect of polyethylene on the thermomechanical properties of green rubber mixes based on 1675N butyl rubber and SKEPT-50 ternary ethylene--propylene copolymer rubber.
The article presents an investigation into the effect of low-density polyethylene (LDPE) and high-density polyethylene (HDPE) on the properties of green rubber mixes based on butyl rubber 1675N and ternary ethylene-propylene copolymer rubber SKEPT-50. An increase in cohesive strength was found in the rubber mixes following the introduction of both low-density and high-density polyethylene. It also leads to a slowing down of the mobility of the polymer macromolecules.
