Described herein are thermoplastic vulcanizates comprising thermoplastic resin, an at least partially vulcanized rubber dispersed in the thermoplastic resin, and process oil. The process oil in the thermoplastic vulcanizate may be selected from extension oil, free oil, curative-in-oil, and/or combination thereof. At least a portion of the process oil in the thermoplastic vulcanizate is a low aromatic/sulfur content oil and has an aromatic content of less than 5 wt%, and a sulfur content of less than 0.03 wt%, based on the weight of that portion of the process oil. The thermoplastic vulcanizate exhibits improved gravimetric fogging properties. |
