Stobicast® HC

High Performance Hot Cast Elastomer Polyurethane Systems

Within almost all industries, hot cast polyurethanes are used to create many technical and commercial products. Stobicast® HC products are prepolymers that work as a two part system when paired with a Stobicast® HC Curative. The products are mixed and poured in a heated mold to create a solid elastomeric product. The Stobicast® HC systems offer various hardnesses and wear resistance suitable for a wide variety of applications from mining to construction.

Selecting the product most appropriate for your application is critical to maximizing the physical properties in your product. Customization of physical parameters are common to meet customer specific requirements.
