These dimpled sorbents are constructed with 1 ply of meltblown polypropylene. Pads and rolls are universal so they are used to absorb oil, water and water-based chemicals. Dimpled pads and rolls share the same features as our bonded-SM pads and rolls without the added layer of spunbond. By not adding the extra layer of spunbond, it makes the pads and rolls more economical. The dimpling process increases the strength and durability of the pads and rolls so they can be perforated like a paper towel. Perforations will help reduce waste and allow you to use the exact amount needed for the job.
