Meltblown Oil-Only Stillwater Booms measure 20'-long with a 5" diameter, with 2 booms included per bale. MBT's oil-only booms are oleophilic and hydrophobic to restrict marine-based oil spills from spreading while absorbing hydrocarbon-based fluids (oil, gasoline, diesel, hydraulic fluids, etc.) at the same time. These white-colored booms are designed to link together to form a continuous absorbing barrier around the perimeter of a spill, allowing the use of pads, rolls, and sweeps to do most of the work by absorbing the interior of the spill, and these water-repellent, 5 booms absorb an average of 28 gallons per bale, typically used in still or slow-moving waters. These absorbent booms are maufactured using the highest quality materials, allowing each boom to be strong enough to withstand the elements, and the combination of each unit's components, including a sock and net covering, produces the finest boom in the industry, consisting of metal O-ring fasteners, metal snap hooks, a polyester net, a polypropylene inner sleeve and rope stabilizer, and a meltblown polypropylene inner filler.
