TPV product 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.Nylon based TPSiV™ (1180-50D) has found use as the jacketing material in automotive brake cables due to its excellent temperature and chemical resistance.
