LAST-A-FOAM® FR-4800 TOOLING FOAM BOARD
LAST-A-FOAM® FR-4800 is a high-temperature tooling board with low CTE that can be used with high-temperature resin systems, such as vinyl esters, epoxies and BMIs, in high-pressure autoclaves and fiber-reinforced composites.

It can withstand peak temperatures up to 480°F (249°C) and continuous use temperatures up to 400°F (204°C). The FR-4800 tooling board is significantly better than other plastics in the market because it does not warp or twist even at elevated temperatures. It will not change shape throughout the course of thermal cycling, preventing out-of-tolerance parts. Furthermore, its predictable and repeatable CTE makes it easy to calculate a tooling correction factor. This helps improve the ability to produce high-tolerance parts, which is especially important in the production of parts for the aerospace, defense and automotive industries.
