TPSiV® Thermoplastic Elastomers


A patented thermoplastic silicone vulcanizate technology 

When you combine the strength, toughness, and abrasion resistance of thermoplastic elastomer with the soft silkiness, UV and chemical resistance, and colorability of silicone, you get DuPont™ TPSiV®. Durable, yet both silky and non-tacky (dirt-resistant), TPSiV® delivers exceptional performance and aesthetics.

TPSiV® products incorporate vulcanized silicone in a thermoplastic matrix and can be customized for specific applications and can be recycled and reused in your manufacturing processes. This makes them remarkably versatile and reliable for a range of applications, including:

  • Wearable electronics
  • Portable speakers and accessory cases for consumer electronics
  • Flexible pipe connections in potable water systems 

Performance benefits achieved with TPSiV® include:

  • Unique soft touch and silky feel 
  • Abrasion and scratch resistance 
  • Lower coefficient of friction 
  • Heat and UV resistant
  • Stain resistance
  • Portfolio with a broad range of hardness
  • Contribute to sustainability actions 
  • Safe to use on direct skin contact applications
