Special Materials Brushes
Spiral Brush offers a wider selection of materials and the ability to manufacture industrial brushes according to the requirements of the individual application. In addition to our standard materials described elsewhere, Spiral Brush offers the following materials for special brush situations:
Polyethylene Brush Filament: Used in high moisture-content situations such as car-washes and fruit & vegetable polishing, where a softer but durable filament is required. Polyethylene is not very abrasion resistant, nor is it recommended for elevated temperatures. Available upon request in diameters from .006” to .060”.
PPS Brush Filament: Also known as Polyphenylene Sulfide, it offers a melting point of 550°F, can be used for extended periods at temperatures up to 428°F, and so it is useful in high heat situations where a wire filled brush can not be considered. It has good solvent resistance, does well in most acids, and is particularly suited for high temperature steam, fuels, and oils. Special grades may also be used in food and medical applications.
Brass Plated Steel Wire: When used in brushes, brass plated steel wire is prized for its resistance to corrosion, relatively low cost, conductive brass coating, and high fatigue properties. Originally designed for applications such as hose-reinforcement and tire cord, this wire has found applications in industrial brushes for wire descaling and tire re-tread preparation.
Nickel Silver Wire: An alloy of Copper, Nickel and Zinc, it offers mechanical properties between brass and bronze. It is highly resistant to most chemicals and offers about 6% the electrical conductivity of copper.
Aluminum Wire: Offers light weight, resistance to corrosion, is conductive to static and electricity, and is relatively economical. However, aluminum wire does not offer very good bend recovery as it tends to bend and take a set. Use only in special situations when its benefits warrant consideration.
Galvanized Steel Cable: This wire construction offers the stiffness of a heavy gauge wire, but the flexibility of the many finer wires that make up the cable. The galvanic coating provides corrosion protection in certain challenging applications.
