LAST-A-FOAM® FR-4700 High-Temperature Tooling Board Series.
These high-density epoxy-urethane tooling boards withstand peak temperatures up to 400° F (200°C) and continuous-use temperatures up to 350° F (177°C). Affordable and dimensionally stable, this rigid foam board is ideal for prototype machining, high-temperature curing prepregs, vacuum forming, pattern making, master model making, small production runs, monolithic or large-mass tools where traditional metal dies are cost-prohibitive.
