work Universal is used when there is a risk of high wear from the top, e.g. in front of processing machines or walkways, but where you still want an absorbent that has a good and fast absorption capacity. Thanks to the fact that there is no surface layer on the underside, the mat lies still on high-gloss floors. work Universal absorbs all types of liquids, petroleum, alcohols and water-based, non-acidic. Floats on water even when saturated with liquid. Rolled items can be mounted in a floor or wall rack for easier handling.
SM stands for Spunbond+Meltblown and is a material that has a coating on the top side. This makes it resistant to wear and tear and fiber release on the top, but can maintain a fast and high absorbency underneath. This material is best suited where you need an absorbent with a fast and high absorption capacity, but which can also withstand the hard wear from above, such as pallet trucks and foot traffic.
