SORTA-Clear™ Series
Water Clear Translucent Silicone Rubber
SORTA-Clear™ Series rubbers are near-clear translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage and feature high tensile and tear strength. These silicones are often used to make one-piece cut block molds where the original model is extracted by cutting. A variety of materials (such as wax, gypsum, resins, etc.) can be cast into molds made with Sorta-Clear™ silicones.
SORTA-Clear™ 18, SORTA-Clear™ 37 and SORTA-Clear™ 40 are certified SKIN SAFE and FOOD SAFE. They can be used to create medical devices, prosthetics and other skin-contact appliances and also for culinary applications including casting chocolate and other confections.
