Sponge Rubber Expansion Joint 3/8″ x 3’X10′

SPONGE RUBBER EXPANSION JOINT is produced to a uniform thickness and density from gray-colored, top-quality, blown sponge rubber. It is easily compressed and has a recovery of 95% or more of the original thickness and a density of not less than 30 pounds per cubic foot (480.56 kg per cubic meter). SPONGE RUBBER EXPANSION JOINT is frequently used on bridge structures and sewage treatment plants that undergo rapid changes in temperature. Because of its excellent recovery capability during wide temperature variations, SPONGE RUBBER is used around supporting pillars, drains, hydrants, lamps and signposts, as well as in isolation applications or between materials having dissimilar coefficients of expansion.
