TPSiV® Thermoplastic Elastomers


Durability, aesthetics, temperature resistance, and UV resistance are demanding hurdles for product designers 

TPSiV® is a tough and versatile solution to these challenges. It brings together the strength and abrasion resistance of TPEs with the softness, UV and chemical resistance, and colorability of silicone. With TPSiV®, designers can elevate their products  to a premium level.


Explore the possibilities with DuPont TPSiV®

You can rely on TPSiV® for an unparalled range of choices and benefits. Durable, yet both silky and non-tacky (dirt-resistant), these materials deliver exceptional performance and aesthetics. TPSiV® products incorporate vulcanized silicone in a thermoplastic matrix. They can be customized for specific applications and recycled and reused in your manufacturing processes.

Applications include wearable electronics, portable speakers and accessory cases for consumer electronics, flexible pipe connections in potable water systems, and ergonomic parts, such as handles or any application that utlizes soft-touch overmolding.
