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spirals (such as in a sea shell charm) without complicated multi-part inserts that are strong and elastic enough to be withdrawn from wax patterns 100’s of times. 

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 and can be used alone or used as an insert for special projects.
