Precision Board or Proto Foam, is a closed cell polyurethane foam, manufactured in a process that does not use the fillers and additives used in Modeling and Tooling boards. Precision Board is suitable for use in a variety of applications such as; pattern and model making, layup tooling, thermoform tooling, sign making, industrial design, and sculpture. Precision Board can be cut with wood or metal working tools. It is very easy to machine, non-toxic, grain free, and freeze/thaw stable. It has a low CTE, is not affected by most common solvents, and does not outgas.
Precision Board comes in standard sheet sizes of 4’ x 8’ or 2’ x 8’. Stock densities are 6, 10, 15, 20, 30lb/ft². 6-15lb densities are ideal for hand sculpting or applications that require low weight. 15 lb and up are best for applications that require high surface detail or more durability. A very wide variety of densities from 4 lb/ft² up to 75 lb/ft² are available by special order.
