Two-Part Liquid Urethane Plastic Products for Tough, Precise Cast Parts

Silpak’s liquid polyurethane plastics are high-performance, two-part systems engineered for durability and precision. With low viscosity for easier casting and minimal shrinkage, these plastics cure into tough, impact-resistant parts with strong heat tolerance. They are ideal for prototyping, part replication, and industrial applications, and the finished material can be machined, sanded, or drilled.

Clean Casting with Low Viscosity Flow

Fill fine details and complex molds with less effort and fewer hiccups.

Our polyurethane plastics pour smoothly, helping you capture sharp features and consistent geometry. Low viscosity supports cleaner fill and fewer casting issues, especially in intricate molds or thin-wall designs.

 

Minimal Shrinkage for Dimensional Accuracy

Produce parts that stay true to size and shape after cure.

These two-part urethane plastics are formulated to reduce shrinkage, which helps maintain tight tolerances for prototypes and replicated components. The result is a more predictable fit, alignment, and repeatability.

 

Durable Parts That Are Easy to Finish

Tough, impact-resistant castings you can machine and refine.

Once cured, the material delivers strength and heat tolerance suited for real-world use. It also finishes cleanly, so you can drill, sand, or machine parts to spec for production-style performance in industrial environments.
