MeltBlown pads and rolls feature loose stacked-weave construction that increases the surface area on spills. They start absorbing on contact, saving you time in critical situations. The hydrophobic fibers repel water (and float) while only absorbing oils and other hydrocarbons. Bright white color makes it easy to see when they are completely saturated save money by not throwing them away too soon. Ideal for outdoor spills especially on water! 15" x 19"
