MOLD RUBBER CASTALDO ECONOSIL SILICONE RUBBER STRIP 5LB BOX
CASTALDO JEWELRY MOLDING RUBBER
CASTALDO Jewelry Molding Rubber has been the industry standard for more than 40 years. It continues to be the best jewelry molding rubber available for lost wax casting. Available in white label, gold label, "no-shrink" pink, high-strength silicone and econosil.
White Label - The industry standard. A soft, pliable natural gum rubber.
Gold Label - This rubber contains more natural gum than the white label making it softer and more pliable. Great for intricate molds.
No Shrink Pink - Eliminates shrinkage without the need for expensive, messy, and time consuming liquid compounds. No-Shrink Pink can be combined with regular CASTALDO white or gold label for greatest economy. Since No-Shrink Pink requires special times, temperatures and procedures, experience, skill, and experimentation on the part of the user is required to achieve optimum results.
