Use PlatSil® Series liquid silicone rubbers to manufacture high-performance silicone molds and silicone parts.
PlatSil® rubbers are platinum-cured (also known as addition-cure), room temperature-curing silicones that cure to flexible, high-strength rubbers. PlatSil® molds offer excellent release properties and release agent is not necessary when casting most materials. Compared to tin-cured silicone rubbers, platinum-cured silicones exhibit long library life and low shrinkage on cure.
Silicone rubber is an excellent mold material, but select silicone products are also widely used as a casting medium in applications including medical modeling, special effects, and orthotics.
