FILL MATERIALS

Proex

This material is highly efficient as an all-purpose filament for indoor and outdoor sweeping applications, including damp or humid environments. It is not recommended for high-temperature sweeping applications. Proex is polypropylene and derives its name from the X-shape of the bristle. A mixture of Proex and Crimped Wire is the most versatile and widely used filament combination. Our standard Proex is a mixture of three diameters, .015″/.025″/.035″. We also offer stiffer options in .035″/.055″ and .055″.


Nylon

This highly productive filament has an excellent brush life in dry sweeping conditions. Nylon performs well on rough surfaces and in high-temperature environments because of its durability and high melting point. As a more flexible material, Nylon is longer lasting in scrubbing applications. Performance is less when conditions are wet or humid. Our standard Nylon for sweeping is a .030″ diameter and for scrubbing, .018″ and .025″. We offer other diameters ranging from .010″ to .060″ and in grades 6.0, 6.6 and 6.12.


Poly

The most popular filament in scrubbing applications, Poly is efficient for use with most soils and surfaces. Although Poly is more economical than Nylon, it is not recommended for sweeping high-temperature debris. The most popular diameter in our cylindrical brushes is .025″ but we also offer a stiffer version in .036″ and a softer version in .016″.


Polyester

Polyester has similar characteristics to Nylon. It has a high bend recovery and very good abrasion resistance for sweeping. In scrubbing applications, it offers excellent resistance to water and chemicals.


Natural Fiber

Union is a natural fiber comprised of a mixture of Tampico and Bassine fibers. It is highly efficient for dust control and sweeping fine debris. It has a relatively shorter wear life versus other synthetic materials. For sweeping, Union is normally mixed with wire to provide more stiffness. Tampico can be used alone as a natural fiber for scrubbing as it offers exceptional water retention and superior heat and chemical resistance.


Crimped Wire

Wire is used in applications needing extra cutting action for heavy duty sweeping of compacted dirt or debris. It is normally mixed with Proex or Union filaments. Recommended for low dust sweeping on unsealed surfaces when used alone.


Grit

This Nylon filament is impregnated with silicon carbide grit particles. Our grit filaments are offered in .070″/46, .050″/80, .040″/120, .035″/180, .022″/120, and .018″/500. The two numbers designate the filament diameter and the grit particle size. The first number is the diameter and the larger the diameter, the stiffer the bristle. The second number is the particle size and, like sandpaper, the smaller the number, the more aggressive the scrubbing.
