New families of thermoplastic vulcanizates (TPVs) were commercially introduced in early 2003 offering 150 deg C heat and oil resistance in excess of 3000 hrs. These TPVs are based on a continuous phase polyamide thermoplastic matrix and dynamically vulcanized polyacrylate (ACM) elastomer. Applications have a broad interest from underhood automotive to industrial applications. The heat and oil resistance of a commercialized TPV from this family will be compared at 150 deg C to conventional and silicone-based TPVs in addition to an ethylene-acrylate (AEM) thermoset elastomer, all of similar initial physical properties. Degradation after 175 deg C spike temperature exposure to air and an assortment of automotive fluids will also be compared, Finally, an overall comparison will be made to qualitatively measure the equivalency of these materials in manufacturing and end use application.
