Meltblown Medium-Weight FMF Composite Universal Rolls measure 15" x 150', with 2 rolls included per bale. MBT's quick-absorbing FMF rolls are a 3-ply composite of fine fiber, meltblown, and fine fiber polypropylenes, and these gray-colored, univeral rolls absorb most aggressive (acidic/caustic) and non-aggressive fluids (oil, water, glycols, etc.). These 3-ply, middle-weight rolls are used to cover long stretches of a spill, and FMF composite products, MBT's most popular, can be used for virtually any in-plant application. The fine fiber polypropylene of this sorbent is tissue-paper-thin, though it's also durable and super-absorbent, and the ultra-thin fibers form a microscopic, tacky surface that allows this product to grip cement floors and remove residual fluids. The soft, non-linting, and porous texture of this highly-absorbent sorbent also grabs fluids and draws them into the lofty, fibrous center of the fabric.
