A specialty nitrile rubberl/polyamide (NBR/PA)blend-type thermoplastic vulcanizate (TPV)was prepared from NBR and PA by dynamic vulcanization technique, and the mechanical properties of TPV were measured. The results show that this TPV has very high tensile strength and hardness, as well as good resistances to solvent and aging. The tensile strength, hardness, permanent set, and resistances to hot oil, solvent and hot oxygen aging increase with the increase of PA level in the blends, while the elongation at...
