Introdiction of Polyurethane Rubber Material

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.
