SYNTHETIC

Nylon: One of the best general-purpose filament materials, nylon is a good choice for contact with oils (petroleum and vegetable), alcohols, strong and dilute acids and dilute alkaline. Durable, resistant to common chemicals, excellent bend recovery and abrasion resistance.

Polypropylene: “Polyprop” is good for wet or dry applications and is unaffected by most oils, acids, solvents, alcohols, and chemicals. Polypropylene has excellent stiffness when wet, fair abrasion resistance and fair bend recovery. Because it has very low water absorption, it is resistant to bio-growth. Crimped and straight filaments are available.

METALS

Mild Steel: High carbon steel wire with excellent fatigue resistance.

Brass: Softer wire as compared to steel or stainless steel, this non-ferrous wire is effective in static dissipation applications.

NATURAL

Tampico: A medium-soft texture, resistant to heat and chemicals, and highly water absorbent. Most often used in light scrubbing and washing applications and wiping wood products.

Wildebeest: Depending on bristle length, is relatively soft to moderately stiff and is used dry for polishing or scratch-free cleaning. Often used for applying adhesives or in anti-static applications.

Below is a table of properties to assist in the selection of the bristle /  filament to be used.
