Open-celled polyurethane foam
Open-celled polyurethane foam has a density of 8.3 pounds per cubic foot and a compressive strength of 295 to 325 psi. It is useful as a porous spacer in layered insulation and as an insulation material in vacuum tight systems.

Improved reinforcement for openings in difficult fabrics
Plastic film is applied to each side of the fabric and the two films are then fused together with conventional heat-sealing equipment. With the inner area of the fabric cut away, a flexible, sturdy band of material is left around the opening with no raw edges.
