Effect of curing characteristics matching on properties of polyurethane rubber/nitrile rubber blends

Effect of curing characteristics matching of blending polyurethane rubber(MPU) and nitrile rubber(NBR) on properties of MPU/NBR blends was investigated. The results showed that the MPU phase was heat treated at 130 ℃ before the blending process to shorten the vulcanization induction period and made...
