Multibase TPSiV™ 3011-50A Thermoplastic Silicone Vulcanizate

These materials are a novel family of TPV products based on cross-linked silicone rubber dispersed into various engineering thermoplastics. The dispersion of the silicone internal phase is produced by dynamic “vulcanization” or cross-linking of silicone polymers within the thermoplastic organic phase and results in a stable droplet type morphology as shown in the TEM micrograph. TPSiV™ combines the elastomeric performance of silicone rubber with the melt re-processability and thermal and chemical resistance of engineering thermoplastics.Thermoplastic polyurethane based TPSiV™ (3010, 3011, 3111, 3040, 3340 grades) combine the benefits of excellent abrasion resistance from the polyurethane as well as the lower coefficient of friction and improved temperature properties from the silicone rubber.TPSiV™ 3011-50A / 60A / 70A / 85A: General purpose grades designed for both injection molding and extrusion applications. Plasticizer free (except the 50A product), which results in excellent bonding via 2-shot molding or co-extrusion to PC, ABS, PU, and PVC. They display good tensile and tear strength.Information provided by Multibase, a Dow Corning Company
