african bass. An extremely coarse vegetable fiber which is derived from a palm tree growing in West Africa. The reddish brown material is very durable and water resistant and can be used on any wet or dry concrete surface. This fiber is a favorite of maintenance crews because of its light weight and excellent sweeping action.
palmyra. A vegetable fiber derived from the base of the fanlike leaf of the Borassus Flabellifer palm tree in India. Its cinnamon, medium stiff fiber is long lasting and sufficiently rugged to sweep streets, garages, and barns efficiently. Its water resistance makes it an ideal scrub brush.
polypropylene. A strong synthetic fiber that's lighter in weight than other plastic materials. It is resistant to oil solvents and detergents; it will not load, curl, or mat and does a great job sweeping stubborn dirt. Polypropylene will outlast ordinary fibers. Not for use with very hot solutions.

pvc & styrene. Composed of plastic fibers having excellent water holding capacity. Styrene is a little lighter in weight than PVC. Both fibers are heavier in weight than Polypropylene. PVC and Styrene have excellent flicking action and are both heat resistant up to 190 degrees Fahrenheit.
tampico. A vegetable fiber derived from the Agave Lechuguilla, a plant which grows in northern Mexico. The natural color is creamy white, but it is often dyed other colors. Tampico has unique liquid holding and release properties - it will absorb 65% more water than plastic fillings. It has a unique surface roughness due to crystals of calcium oxalate embedded in the surface. There is really no plastic substitute for Tampico. The fiber is unsurpassed in most general sweeping applications, and in all applications requiring liquid retention, scrubbing and surface finishing.
nylex (nylon fiber) 612. A super light, very resilient and durable synthetic fiber. It can be boiled and is impervious to solvents, alkalis and certain acids. This fiber has better water holding characteristics than other synthetics. Its special shape (X cross section) gives it excellent capillarity - that is - moisture moves up the tufts easily. When flagged, this fiber wears down to a natural point giving it a softness that resembles horse hair. (Do not use with mineral acids - these attack the nylon fibers.)
horse hair. The ultimate natural fiber. Produces scratch less, fine dry sweeping. It is used to finely smooth newly poured concrete, and is a perfect sweep for highly polished surfaces.
