This economical Gemini™ Gold silicone mold rubber sheet is formulated to have greater tensile strength and flexibility than most other silicone-based mold rubber. Due to its extremely high tear strength, this formula is ideal for fine, intricate patterns, filigree or items requiring a great degree of “stretch” in the mold when removing the injected wax piece. Count on a long life (even with high-production use) and a shrink rate of just 2.8%. Best of all, this material can be used in the same mold with other types of Gemini mold rubber to add strength to specific high stress areas. Any design with intricate patterns or undercuts will benefit from the extra strength and increased flexibility of Gemini Gold. To use, simply pack Gemini Gold around your master, into any undercuts or crevices, into baskets and so on. Gemini Gold is specially formulated to ensure durable molds that offer years of crisp model reproduction and smooth, high-quality waxes.

All of the qualities you expect—easy packing, easy cutting, smooth molds, perfect pattern reproduction, durability, good memory, manageable shrinkage, serviceability and good shelf life—are delivered in Gemini silicone mold rubber.
