TPSiV® Thermoplastic Elastomers

Arm with smart watch

When you combine the strength, toughness, and abrasion resistance of a thermoplastic elastomer with the soft silkiness, UV and chemical resistance, and colorability of silicone, you get DuPont TPSiV®

TPSiV® products incorporate vulcanized silicone modules in a thermoplastic matrix. But unlike traditional thermoplastic vulcanizates (TPVs), they can be recycled and reused in your manufacturing processes. This makes them remarkably versatile and reliable for a range of applications. Durable, yet both silky and non-tacky (dirt resistant), TPSiV® Thermoplastic Elastomers deliver exceptional performance and aesthetics in products ranging from consumer electronics to plumbing supplies.
