| Abstract: |
| The effects of rubber blending ratio and compatibilizer ionic thermoplastic elastomer on properties of EPDM/NBR blends were studied.The results showed that，when the compatibilizer was not added，the modulus at 100% elongation and tensile strength of blends increased with EPDM/NBR blending ratio decreasing，and the heat oxygen aging resistance and ozone aging resistance decreased，the oil resistance was improved，and the compatibility between EPDM and NBR was poor.After adding the ionic thermoplastic elastomer，the hardness，tensile strength，tear strength and elasticity of EPDM/NBR blends increased，and the compatibility between EPDM and NBR was improved significantly. |
