LAST-A-FOAM® FR-6700 is a CFC-free, rigid, closed-cell, flame-retardant polyurethane foam available in densities ranging from 10 to 25 pounds per cubic foot.

For lower-density foams with comparable physical property characteristics, flammability, temperature resistance and chemical resistance performance, please see our LAST-A-FOAM® FR-3700.

LAST-A-FOAM® FR-6700 meets the requirements of several military specifications, and materials specifications of many aircraft and aerospace manufacturers. If your project or application requires certification, we can supply specification conformance information on request.

LAST-A-FOAM® FR-6700 has temperature resistance suitable for laminating processes in the 250-275°F temperature range.

It exhibits a high strength-to-weight ratio due to its cellular structure and cross-linked resin. Also, because of its closed-cell structure, LAST-A-FOAM® FR-6700 has great resistance to water absorption, and will not swell, crack, or split on exposure to water.

LAST-A-FOAM® FR-6700 is stable, inert, and is resistant to most chemicals and solvents. It is easily worked with common tools, and performs well as a primary structural material, or as a replacement for other materials in a variety of applications.

The last two digits of FR-6700 product numbers describe foam density in pounds per cubic foot. For example: FR-6720 is a 20-lb. per cubic foot foam.

Some typical uses include:

• Honeycomb edge close-out for aircraft interior sandwich panels as used in:
  • Overhead storage bins,
  • Passenger cabin class dividers
  • Galleys and lavatories
• Insulated supports for pipes, walls, footings
• Composite tooling core material
• Core material for snow and water skis, surfboards
• Models and design prototypes
• Vacuum form dies, mold patterns
• Hazardous materials transport packages
• Insulated structural panels
• Core material for boat decking, motor mounts

LAST-A-FOAM® FR-6700 series foams are available in densities of 10 to 20 pounds per cubic foot in 48" x 96" sheets, and in densities from 10 to 25 pounds per cubic foot in 18" x 100" sheets.

Many LAST-A-FOAM® FR-6700 densities are available in large block sizes for special tooling and machining needs. Please feel free to inquire about large block size availability and costs.

Special sheet and block sizes gladly quoted on request.
