New Pig Sheen Clean polypropylene skin oil-only pillow. Proprietary filler cleans up waterborne spills entirely, even the thin, oily residue that's often left behind. Bright white color makes pillows easier to see in outdoor environments and clearly shows saturation level. Can be incinerated after use to reduce waste or for fuels blending. Not recommended for use with acids, bases or other corrosive liquids. Fluids absorbed: oil-based liquids but not water. Recycled content: 90 percent post-consumer recycled cellulose waste. Absorbency: Up to 10 gallon per box. Composition: polypropylene skin and proprietary blend of hydrophobic cellulose with oil-absorbent co-polymers filler.
