The brown mat for pig oil only absorbs oil. The dirt is not visible, so it can be used for a longer time. The brown color is less visible to stains and blends in with most indoor and outdoor environments, making spills and spills less visible than brightly colored mats. Repels water and absorbs petroleum, hydrocarbon and other oil-based liquids. Suitable for frequent washing of floor surface with water. Pigmat has 8 layers of absorbent polypropylene with ultrasonic heat crimping for durability and abrasion resistance. Absorbs oil from the dimples on the surface of the mat and rapidly penetrates the entire mat. The ultra-fine fiber construction has excellent absorbency and holds liquids firmly in place, and the mat wont drip off when you lift it. Rolls are perforated every 10.0 inches (25.5 cm). Perforations are also in the center so you can easily cut it to your desired size.
