Combination Synthetic Fill Wood Block
This is a combination of both thin and thick polypropylene fibers. Polypropylene is very light with excellent resilience to acid and most solvents. Polypropylene has poor recovery from crushing, however, it can be used in hot water and has good wearing properties.
A black Polypropylene border surrounds the stiff red Polypropylene centre which effectively combines medium sweeping of heavier debris.
Ideal on semi-smooth to rough surfaces for medium to coarse sweeping and the fibers are not affected by water, grease, oil and most chemicals.
