With 16 layers of thermally bonded polypropylene, chemical-resistant Fat Mat absorbs up to 56 oz of oils, coolants, solvents, and water per 20 x 16 in. pad. Dimple pattern speeds wicking action across mat and transfers liquids into absorbent inner layers to keep moisture away from surface. Durable when saturated, mat includes melt blown fine fibers that grip floor, and spunbond top layer that will not rip, tear, or fray, even under heavy foot traffic.
