Tapered sleeve, elastic both ends, sonic welded seams, white, 300/case. - Choosing a protective sleeve is critical, since arms are more likely to come in contact with dangerous fluids, compounds and chemicals in work areas, labs and during mixing/cleaning operations. Our sleeve protectors use sonic welded seams down the entire length to maximize barrier protection and eliminate concern about seam failure. With a low particle count, Microbreathe material acts as a high performance barrier to particles, biologicals, fluids and chemicals. The fabric's filtration efficiency is 99.9% to assure contamination from the wearer does not transfer to your critical environment. To keep personnel comfortable, the material exhibits a high rate of heat and perspiration transmission while still containing contamination. For added safety, the soft fabric will stretch before it will tear or puncture. The tapered sleeves are tailored for comfort and to maximize protection.
