TPSiV® thermoplastic elastomers combine the strength, toughness and abrasion resistance of any thermoplastic elastomer with the desirable properties of silicone: softness, silky feel, resistance to UV light and chemicals, and outstanding colorability. These unique materials incorporate vulcanized silicone modules in a thermoplastic matrix, but unlike traditional thermoplastic vulcanizates (TPVs), they can be recycled and reused in your manufacturing processes. TPSiV® 4000-60A SR thermoplastic elastomer is a UV stable material with excellent abrasion and scratch resistance. It exhibits excellent bonding to polycarbonate, ABS and similar polar substrates. It is a product targeted for soft touch overmolding on smartphones, portable electronic cases and wearable electronic devices.
