This high-quality, LTV (low-temperature vulcanization) silicone mold rubber from Nicem® is specially formulated to vulcanize in contact with metal oxides, allowing you to create molds from brass, bronze, copper or silver prototypes. The rubber is ideal for use with a fixed or mobile insert inside a harder rubber; it is resistant to tearing, has no filler dust and works well with vacuum injectors.

Formulated specifically to meet jewelers' needs, helping to create molds from wax or resin models without causing damage to the model, Nicem® silicone mold rubber delivers premium performance with low shrinking rates. The rubber is made from the highest quality polymers and fillers, making it durable and long-lasting.
