A rubber crumb mat that has been flocked is a rubber mat made from rubber crumbs that has been coated with a layer of material, usually nylon, to increase its durability and provide a softer surface for standing or walking on. This type of mat typically has a rubberized surface that is designed to resist wear and tear from everyday use. It also provides a softer surface to stand or walk on, reducing the risk of slipping or falling. The flocking material can also be dyed in different colors to provide a decorative touch to the mat.
