| Abstract: |
| The effects of the TPU/CPE blending ratio，type and addition level of reinforcing agent on the properties of TPU/CPE blend were investigated.The results showed that，when the TPU/CPE blending ratios were 70/30 and 60/40，the compatibility between TPU and CPE was good，the comprehensive properties of the blend were excellent；the processability of TPU/CPE blend was improved by adding reinforcing agent，and as the addition level of reinforcing agent increased，the Shore A hardness，tensile strength and tear strength of the blend increased，the elongation at break decreased；the modified silica possessed better reinforcement effect than carbon black N330 and N550，and the optimum addition level of the modified silica was about 30 phr. |
