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.
Item No.: MCPU-50
Mix ratio: 1.4: 1
Part A color: Yellow
Part B color: Clear
Pour time (mins): 45
Demoud time (hrs): 6-8
Full cure (hrs): 24
Density (g/cm3): 1.05
Mixed viscosity (cps): 1500± 300
Hardness (shore A): 50
Tensile strength (Mpa): 6.1
Elongation (%): 724
Shrinkage: 0
Tear strength (N/mm): 42.1
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. Description of Polyurethane Molding Rubber
