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
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.
