This polyurethane foam is great for applications where an economical, versatile, and stable stock material is desired.

Product Features and Benefits:

  • Fine cell structure
  • Closed-cell
  • Easily painted and bonded
  • Dimensionally stable
  • Grain-free
  • Easily shaped with a variety of cutting processes
  • Densities available from 4 - 40 lbs per cubic Ft.

Common Applications:

  • Proofing NC/CNC machine programs
  • Prototype models
  • Composite core
  • Marine: Stringers, bulkeads, mounting pads, heads, and galleys
  • Solar: panel backing and support, parabolic mirror farms
  • Custom parts
  • Tooling board

Composite Core

LAST-A-FOAM® FR-7100 can be used with multiple densities. There can be high and low densities in one layup, making it an ideal material for composite layups. In addition, this product is available in sheet stock and there is no mold-release in GP's sheet stock manufacturing process.

Marine

LAST-A-FOAM® FR-7100 is formulated to meet the demands of composite boat builders at competitive prices. For Stringers, we recommend the FR-7100 in 6-20 lb per cubic foot densities depending on structural need. For seat mounting pads and steering wheel mounting, we recommend 24-30 lb per cubic foot densities. Lastly, for decks and bulkheads, we recommend 10-15 lb densities of the FR-7100 foam.

Prototypes and Models

LAST-A-FOAM® FR-7100 is an economical polyurethane foam made in 4-40 lb densities. This foam is suitable for hand-carved models, CNC-machined topographical maps, prototypes, industrial patterns, and more. FR-7100 is made in more densities than any other product we offer and large block sizes are available.

Tooling and Molds

LAST-A-FOAM® FR-7100 products have been used sucessfully in tooling applications for many years. This material meets the needs of mold and tool makers because of it's stress free, easy to machine, and has constant density throughout thickness. Generally speaking, if higher strength, greater detail, or increased heat and pressure resistance at process tempeature is rquired, the FR-7100 performs best at a 20 lb per cubic foot density. Typical uses include: composite lay-up tools, drape-forming tools, and vacuum-form tools.

For more information please see the FR-7100 Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS) for specific densities, and the FR-7100 product data sheet.
