- | Thermoplastic vulcanizates (TPV) are part of the thermoplastic elastomer (TPE) family of polymers, but are closest in elastomeric properties to EPDM thermoset rubber, combining the characteristics of vulcanized rubber with the processing properties of thermoplastics. TPV is a dynamically vulcanized alloy consisting mostly of fully cured EPDM rubber particles encapsulated in a polypropylene (PP) matrix. There are almost 100 grades in the S portfolio which are used globally in the automotive, household appliance, electrical, construction and healthcare markets.

- | ==== Early successes ==== | + | |
- | Santoprene TPV enjoyed early application successes in the automotive sector, including rack and pinion boots, due to its flex life, fluid resistance and sealability. In the appliance sector, a dishwasher sump boot made with Santoprene TPV provided good sealing and resistance to heat and fluids. Due to its sealing properties, Santoprene TPV was also successful in the domestic and high-rise construction sectors in applications such as window seals, caster wheels, tubing and small hose parts, electrical connectors and coatings for wire and cables. It was also used in the medical industry as a gasket on syringe plungers. | + | |
