Manufactured from meltblown polypropylene and specially treated, oilskin sheets behave just like on oilskin. They are waterproof but have one important additional feature in that they will quickly absorb accidental oil spills of oil and oil based liquids. The perforated skin allows you to quickly tailor your oilskin to fit any shelf, ledge or sump where oil collects or could be spilled. Dimpled skin increases speed of absorption and adds strength.
