Dow Corning Corporation TPSiV siloxane Elastomers
These proprietary compounds feature crosslinked silicone rubber dispersed within a matrix of TPU or other thermoplastic resin. As a class, TPSiV compounds share a significant set of properties. The silicone rubber contributes resistance to chemicals, UV, and heat; while the TPU phase provides abrasion resistance, bonding, color versatility, and processing simplicity. Because resilience is achieved without using plasticizers, these materials provide luxurious, silky feel and minimize issues associated with volatile emissions or migration.
