Safety-Kleen's 4 in 1 Mat can be used as a pad to catch drips and soak up spills, rolled out to cover large areas, folded along score lines to make a thick, absorbent "sock," or used as a low-lint wiper. It is made of an eight-layer, 100% polypropylene PIG Mat. The 16” width by 150’ length roll is deisgned to absorb oil and fuels, but not water. Its dimple pattern speeds wicking of liquid throughout the mat for faster, easier cleanup, and easy-tear perforations allow for small portions of the mat to be used. Each roll can absorb 17.4 gallons, according to the company.
