Description of Polyurethane Molding Rubber

Polyurethane mold rubbers consist of a Part A and a Part B that, after mixing, cure at room temperature to flexible, high-strength rubbers. Polyurethane rubbers make durable, easy releasing molds for casting plasters and waxes without release agents, but, when used with proper release agents, are also excellent for casting concrete, epoxy, polyester, polyurethane and acrylic.

Features of Polyurethane Molding Rubber

It has excellent processing properties, solid in common temperature, shorter gel time, and regulating color by adding pigment. The ware has good properties of abrasive resistance, hydrolysis resistance, transparent, good resilience, stable dimension.

Applications of Polyurethane Molding Rubber

Substitute for Silicon rubber to make the mould of "cultural stone". It also applies to electrical equipment potting, rubber rollers, Ski and snowboard ,rubber plates, rubber wheels, shoe models and others.


Packing of Polyurethane Molding Rubber
20kg/drum or 200kg/drum


Storage of Polyurethane Molding Rubber

For best results, store products in unopened containers at room temperature (60-90° F/15-32° C). Use products within six months. Parts A and B react with atmospheric moisture and, therefore, should be used up as soon as possible after opening.
