Polyurethane rubbers are two-component systems (base plus curative; A+B) that cover a wide variety of applications at a relatively low cost. They are available for making molds that are poured, brushed or sprayed onto a model
Polyurethanes are easy to use, with many having a simple mix ratio by volume (i.e. 1A: 1B) – no scale required.
Flexible urethane are available in a wide hardness range from gel-like to harder than a car tire and everything in between. [Related: Durometer Shore Hardness Scale Guide]
Urethane have good abrasion resistance and are used to cast abrasive materials like concrete.
Polyurethane rubbers are less expensive than silicones and polysulfides.
