Meltblown Heavy-Weight Dimpled Polypropylene Universal Pads measure 30" x 36", with 50 pads included per bale. MBT's dimpled meltblown polypropylene pads are economical, semi-fibrous pads that have been run through a bonder to create dimple impressions that "tie-down" loose fibers, and these gray-colored, univeral pads absorb most aggressive (acidic/caustic) and non-aggressive fluids (oil, water, glycols, etc.), useful for quick, general absorption in machine shops and manufacturing facilities. These multi-pupose pads are used to quickly absorb the majority of a spill, and the lack of an outer membrane on these single-ply, double-weight pads allows their semi-fibrous texture to grab thicker-viscosity fluids and quickly draw them into the center of the fabric.
