LLDPE/SBS blends in different blending ratios were prepared by melt blending and the relationship between stress and strain was studied.The blends compositions effects on the maximum stress, shore hardness and elasticity were also studied. The results showed that the value of hardness and the maximum stress were reduced with the decreased content of LLDPE.The antagonism effect made the maximum stress of the blends less than the simple sum of each component’s contribution.First compression resilient, secondary compression resilient and three compression resilient had little difference when the content of SBS in blends was 30 phr.Constant strain cyclic stressstrain curves could provide guidance for the compression degree of gaskets.The relationship between stress and composition could provide the basis for determining the gaskets composition.
