ENV® MAXX® Enhanced absorbents are made of highly economical, contractor-grade single-ply meltblown polypropylene for oil clean-up on land or water. White absorbents pick up petroleum-CSsed fluids, paints and non-water soluble chemicals while repelling water - great for indoor & outdoor use. Heavy weight - specifically designed for continuous leaks and larger spills so you use less material. ENV® absorbents are made with MAXX® Technology for superior absorbency and greater strength without the added weight. Non-perforated absorbents offer the greatest absorbency and better tear resistance in high traffic areas.
