SORTA-Clear® 40 is a premium water white translucent silicone rubber (platinum catalyst) that cures at room temperature with negligible shrinkage. SORTA-Clear® 40 has a Shore hardness of 40A and features exceptional tear and tensile strength.
Rubber clarity is especially useful when extracting models via cutting. SORTA-Clear® rubber is ideal for making prototype, jewelry or other molds of any configuration where model visibility is important (i.e. extracting a model from the mold via cutting). Materials such as urethane, epoxy or polyester resins can then be cast into SORTA-Clear® silicone without application of a release agent. Other materials such as wax and low melt metal alloys can also be cast into SORTA-Clear. SORTA-Clear can be pigmented with SILC Pig silicone pigments.
In this example, a pour-on mold of a cell phone is created using Sorta Clear 40® silicone rubber.
Sorta-Clear® 40 mold allows you to see the model clearly.
The clarity of the rubber allows you to cut out the model without damaging its surface.
