Product Description

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

1. High strength
2. Low to moderate cost
3. Many versatile formulas

Applications of Polyurethane Molding Rubber

1. Casting most materials.
2. Acceptable for some resins.
3. Not acceptable for molten metals.
