Material

Rubber-like Polyurethanes

Vacuum casting with rubber-like polyurethanes and silicone molds is a fast, cost-effective way to produce high-quality prototypes or small series of end-use parts such as grips, seals, and non-slip surfaces. Our wide range of polyurethanes offers a choice of properties and finishes, making it possible to select the material that is closest to the original or end product.
