Meltblown Booms are non-linting and are sock and net construction to ensure that all particulate stays safely inside the boom. Each boom is linkable and comes complete with end rings, snaps and a sturdy rope running their length. They contain high-quality, all-synthetic, high-absorbency fill blended with a flotation agent. Tests indicate that this agent makes the fibers more porous allowing them to absorb 10% more oil than regular meltblown booms. Booms are 5 x 10 feet, 4/Pack. Sold as Pack.
