Polyurethane Resin

Polyurethane resins, also known as PU resins, are among the most versatile and widely used materials for casting processes. Easy to handle, they offer an excellent balance of mechanical performance, fast curing times, and user-friendly processing.
Samaro, a specialized distributor of industrial materials, offers a comprehensive range of polyurethane resins through the RenCast brand, known for its high-quality and reliable technical formulations.
RenCast PU resins enable the production of materials with varying properties, from soft polyurethane elastomers to high-strength rigid resins. They are particularly suitable for mold making, small series replication in silicone molds, tooling fabrication, part repair, and the production of functional prototypes.

Typical applications of RenCast polyurethane resins include:


Vacuum casting for accurate reproduction of technical parts;


RIM (Reaction Injection Molding), a low-pressure process for manufacturing complex components;


Rapid prototyping, ideal for design validation or functional testing;


Foundry mold and core box fabrication for sand casting processes;


Industrial model making and the creation of scale models or decorative parts;


Fast-setting casting for producing small series parts with short lead times.


Thanks to Samaro's expertise, users benefit from technical support in selecting the most suitable polyurethane resin for their application—whether in design offices, prototyping workshops, or industrial production environments.
