Even if it has excellent oil resistance, weather resistance, and tensile strength (Comparative Example 2), the vulcanization adhesion with the EPDM rubber composition is poor, and it is difficult to obtain a product that is sufficient for practical use. I can't.

By blending 2 to 20% by weight of 23.5% SBR, the vulcanization adhesion with the EPDM rubber composition is improved,
This shows material failure of EPDM rubber with low strength.
