These socks feature a tough spun-bond outer sleeve that has a durable heat sealed seam running its entire length. The absorbent core is secured into the sleeve at each end with a durable plastic clip for the Chemical version and metal for the Maintenance and Oil only versions.
The Oil only sock is filled with an absorbent polypropylene core that is made from recycled material. This core will absorb just oil-based fluids.
For the Maintenance and Chemical socks this tube is then filled with Super Absorbent Flake. This is a new product technology and has many benefits. First and foremost it is completely inert and not harmful (unlike polyacrylate), secondly it absorbs and holds liquids without any of the slippery or leaking gel problems. Another excellent feature of this new technology is that because it is inert the flake is able to absorb most hazardous chemicals. So not only is Super Absorbent Flake the world's first super absorbent for chemicals, it also out performs more traditional Maintenance and Chemical sock and pillow absorption rates by up to 50%!
