Urethane Casting Rubber

Urethane Casting Rubber: High-Performance Material for Detailed Prototypes and Parts

When creating high-fidelity prototypes, functional parts, or short-run production items, selecting the right material is paramount. This is where Urethane Casting Resin excels. Our premium Urethane Casting Materials are engineered to deliver exceptional detail reproduction, durability, and a range of physical properties that mimic production-grade plastics and rubbers. To achieve optimal results with these advanced materials, a controlled Urethane Casting Process is essential, often supported by a reliable Urethane Casting Machine for consistent mixing and degassing, ensuring bubble-free casts every time.

Our specific formulation of Urethane Casting Rubber is a two-part, liquid polymer system designed for vacuum casting applications. It is renowned for its high tear strength, excellent abrasion resistance, and the ability to capture extremely fine details from master patterns. This Urethane Casting Rubber exhibits low viscosity for easy pouring and de-airing, along with a controllable pot life and cure time to suit various project scales and complexities. It cures at room temperature to form a solid, resilient rubber that can withstand functional testing and repeated use.
