Product 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
