PIG Sheen Clean Oil-Only Absorbent Sock cleans up the thin, oily residue floating on water that other absorbents leave behind. Very strong filler blends high-capacity recycled cellulose with a copolymer that pulls in thin, filmy sheens of oil. Ideal for long-term deployment to remove sheen after oil-based spills or absorb oil residue in retention ponds, catch basins, tanks, and more. Polypropylene skin resists tearing; reduces dust, and holds in liquid, even when saturated. Attached string allows socks to be tied down, tied together, or dipped into tanks. Absorbs and retains oils and oil-based liquids, including lubricants and fuels, without taking in a drop of water. The bright white color makes sock easier to see in outdoor environments and clearly shows saturation level. Skin is UV- resistant up to 12 month, which provides long-term outdoor use without degradation. Can be incinerated after use to reduce waste or for fuels blending. Not recommended for use with acids or bases
