High-performance High-elasticity Silicone Rubber


Instruction Video
A brief video to show how to use Castaldo SuperStretch Jewelry Molding Rubber.

Molds that normally require many parts to release complicated or difficult patterns can now be done easily and simply.

Castaldo SuperStretch™ is able to mold hollow gold spirals (such as in a sea shell charm) without complicated multi-part inserts that are strong and elastic enough to be withdrawn from wax patterns 100’s of times. Just look at the shine! SuperStretch High Shine Finish means less polishing. Cuts like butter. Easy mold packing / easy mold cutting. Low rubber shrinkage – only 1.3%. SuperStretch is compatible with other Castaldo silicone molding rubbers – can be used alone or used as an insert for special projects.
