Multibase TPSiV™ 3111-70A 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™ 3111-70A: Designed for good stability in water contact applications and other aqueous solutions. Plasticizer free, and is currently being used in both NSF61 and FDA (Section 177.2600: 'Rubber articles intended for repeated use') applications.Information provided by Multibase, a Dow Corning Company
