Mold Making and Casting | RTV Silicone Rubber

A full range of RTV Silicone Rubbers is available from Innovative Polymers for casting durable molds that are suitable for building accurate prototypes for a variety of applications. The RTV Silicone Rubbers exhibit low to no shrinkage and provide for outstanding replication of fine details.

Innovative Polymers supplies two different types of RTV Silicone Rubbers to meet customer needs:

  • P series Silicone Rubbers are addition cure systems that produce molds with virtually no shrinkage. Curing of the materials may be inhibited by tin, sulfur or amines, occurs in total confinement and can be accelerated with heat. P series RTV Silicone Rubbers produce molds with excellent heat resistance and elongation.
  • GI series Silicone Rubbers cure via condensation at room temperature over virtually any surface. The systems feature very high elongation and tear strength.
