Category
New families of thermoplastic vulcanizates (TPVs) were commercially introduced in early 2003 offering 150°C heat and oil resistance in excess of 3000hrs. These TPVs are based on a continuous phase polyamide thermoplastic matrix and dynamically vulcanized polyacrylate (ACM) elastomer and are marketed under the Zeotherm® trade name. 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°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°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.
