Engineered in Akron, Ohio USA, the polymer capital of the world. Akron mold rubbers deliver controlled shrinkage, excellent cutting qualities, high tear resistance and elongation, and excellent fill and detail reproduction.
Because the formulations contain certain waxes, oils and antioxidants, your molds will enjoy many, many years of production life. Modern chemistry permits an uncured shelf life of 7 years or more, finished life of over 20 years.

Akron Jewelry Rubber should be vulcanized at 310°F (154°C) for 7-1/2 minutes per layer of rubber.
