Polyurethane Smooth Finish Tooling Foam


HIGH DENSITY POLYURETHANE FOAM

Fine cell polyurethane foam supports the most intricate detail while eliminating extra prep work. With an even-smoother surface finish than our FR-4500 tooling material, it is superb for precision tooling applications, or as modeling foam. Advanced microcell technology creates a grain-free, ultra smooth exterior for painted finishes, significantly reducing process time. What’s more, its finer cell structure is comparable to higher-density products without the added cost and weight.

Unlike more dense glass microballoon-filled syntactic foams, this material greatly reduces tooling wear. The high-density polyurethane foam is easily worked using CAD/CAM routers and CNC machines – or the simplest woodworking tools. The FR-4600’s exceptional machining characteristics also make it an efficient material to create intricately patterned masters for composite and layup tools, and for mold and foundry patterns.

Smooth Finish Foam for Tooling & Molds

FR-4600 Microcell Board, designed for tooling use up to 200°F, is well-suited for layup tools with low-temperature curing prepregs, and other low-temperature processes. This superfine tooling material produces remarkably crisp edges with exceptional dimensional stability.

Fine Cell Foam for 3-D Signage, Prototypes and Models

Our FR-4615 & FR-4618 are excellent edge definition paired with the microcell ultra smooth surface, makes our FR-4600 material an outstanding alternative to wood in outdoor sign boards and display manufacturing. With its superior cell structure, this board accommodates very fine surface finishes using virtually any coating system. Please visit our distributor SignArts for more information or samples.
