Hytrel® (TPE) Thermoplastic Polyester Elastomer, has exceptionally high tear strength, abrasion resistance, modulus, and a wide temperature range. Hytrel® is not compatible with cresols, phenols, and highly concentrated acids. Due to its higher hardness and modulus, it is suitable for high pressure service where extrusion might be an issue. Seals made from this material can be difficult to install. Also, care must be taken not to damage the seal lips during assembly into the gland.
