STYROFOAM SMALL CELL (BLUE) 1/2"X24"X48&

Low density (2 lb./ft3). Tight closed cell structure leaves no voids between the cells. The result is high compressive strength and unequaled resistance to water penetration. Has excellent resistance to bases, salts, alcohols and most acids but not to petroleum based solvents. Cuts smoothly with a hot wire for airfoil shapes.
