【Abstract】 The rheological behaviour of the LDPE/EPDM blend melt with blowing (or foaming) agent AC and cross -link agent was studied in this paper. The influence of shear rate on the viscosity and temperature sensibility was also discussed in details. It was shown that as the content of cross - link agent was increased the apparent viscosity of the melt was raised and the sensitivity of the melt flowability to temperature became more obvious in the range from 170 to 190℃.更多还原
