Material

ABS-like Polyurethanes

Vacuum-cast ABS-like polyurethanes resemble injection-molded ABS, making them ideal for high-quality prototypes or small series of end-use parts such as product housings or covers. Our wide range of materials offers a choice of properties, including materials that are flame retardant, food-safe, and UV-stable, as well as a variety of finishes. For use with silicone molds.
