Hazmat absorbent pads are used to aborb acids and bases, aggressive chemicals, oils, solvents, citric acid, water-based fluids and sodium hydroxide. These are bonded meltblown pads that allow for perforation and increased durability. They feature an extra layer of spunbond polypropylene that make the pads lint-free on the top and highly absorbent on the opposite side. The lint-free side is great for wiping down tanks, tools, walls, etc. They are 15"x19" and come in both a heavy weight pad and a light weight pad. The heavy weight come 100 pads/bale and the light weight come 200 pads/bale. They are perforated every 7.5" vertically and 19" horizontally.
