These Chemtex Universal Bonded Sorbent Pads absorb oil, water, and water-based chemical spills quickly and efficiently. Each pad is constructed with 2 plies of polypropylene: spunbond and melt-blown. The bonding process increases the strength and durability of these pads. Perforations help reduce waste by allowing you to use the exact amount needed for the job. These pads offer the best of both worlds: a lint-free top side for cleaning and wiping tanks, tools, walls and more without leaving lint, and a melt-blown side for quickly absorbing fluids.
