GOAT HAIR: A very fine, soft hair with limited elasticity. It has a natural kink that cannot be
straightened. Typically used for short, soft bristle brushes like cosmetic brushes and electronics
industry brushes. Available at Gordon Brush® in natural black and white for most applications.
Brushes can be dyed if required.
HOG BRISTLE: Relatively scarce and expensive. This material has characteristics that set it apart
as the best natural filling material for a wide variety of bristle brushes. Each strand of bristle has
a natural taper from the butt or flesh end to the tip, giving it resilience not found in other hairs.
In addition, the tip end of each bristle is naturally split into two or more branches called the flag.
Hog bristle has a slightly stiff to very stiff texture and is off white or black in color. This bristle is
excellent for ESD brush applications. Chung King hog bristle is the stiffest hog bristle available. It
also has excellent durability and water resistance.
HORSEHAIR: Horsehair is a medium to high cost material. Tail hair is stiffer than mane hair. Its
soft to slightly stiff texture provides for scratch-free cleaning with very good durability. Horse
hair is highly absorbent due to the many tapered scales along its length which allow it to carry
liquids (water, ink, paint) very well. Because it is not resistant to acids or alkalis, it is used for
buffing, cleaning, dusting, and finishing in a variety of bristle brush styles: floor sweeps, shoe
shine brushes, tin handle acid brushes, counter dusters, and window brushes. It is also excellent
for ESD brush applications but it does not hold a static charge. Its heat distortion temperature is
CAMEL HAIR: Camel Hair brushes are not made from camel hair. Rather, it is a generic term
used for lower priced, soft hair mixtures of different hairs such as pony, goat, squirrel, or sheep.
It’s commonly used for lower quality, less expensive artist brushes.
OX HAIR: In proportion to its diameter, ox hair is perhaps the stiffest of all soft hairs, and is very
strong and resilient. Ox hair comes from the ears of oxen and has a springiness or snap similar to
sable hair. The tips, however, are quite blunt when compared to sable so fine tip brushes are
not possible. Ox hair is particularly sought after in artist or detail brushes for fine lettering,
striping and marking brushes.
RED SABLE: The hair of the red sable is the most valuable of all soft hairs. It is very fine, has
strong, sharp points, great elasticity, and carries color well. Red sable hair makes the finest
artists' brushes, being particularly suited for use with oil paints and heavy-bodied sign-writing
materials and works best for fine lettering. Pure red sable hair has a perpetual taper, creating
the finest point possible on a bristle brush.
SQUIRREL: This hair is divided into blue squirrel and Canadian squirrel. A very fine hair used for
applying thin lacquers, Japan colors, light-bodied varnishes, and for general artwork, lettering
and striping, as well as cosmetic brushes and forensic brushes. Blue squirrel hair is exceptionally
soft and extremely expensive.

BASSINE: BASSINE: A select grade of Palmyra fiber, but stiffer, more durable and more resistant to water
than natural Palmyra. This bristle is very dark brown in color. Its coarseness and good water
resistance make it ideal for stiff scrub brushes and is widely used in conveyor cleaning brushes.
PALMETTO: Produced from the Florida Palmetto Palm. It is coarse, reddish in color and oil
treated for wet applications. Palmetto is a quality bristle brush fiber, widely used in deck and
can scrubs, garage sweeps, whisk brooms, etc.
PALMYRA: A cinnamon colored fiber produced from the base of the leaf stalks of the India
Palmyra palm. It has a medium stiff to stiff texture and is light to dark brown in color. It is finer,
less stiff, more brittle, and of lower quality than bassine. Used in garage floor brushes, fender
washing brushes, deck brushes, and scrub brushes.
TAMPICO: TAMPICO: Produced in Mexico from the stalk of the Agave plant. This bristle has a soft to
medium texture and is off white in color. It is often dyed and blended to give the desired effects
to a bristle brush. It is heat, alkali, and acid resistant. The porous fibers absorb water and work
wet or dry. This material is more aggressive than nylon or horsehair. It is used for removing
surface particles and tool marks, dusting, wet scrubbing, cleaning, and spreading liquids. It is
excellent for removing light feather burrs and for light edge blending when used with a
compound. Its heat distortion temperature is 283º F.
UNION FIBER: A mixture of two or more materials – usually tampico and palmyra. This material
has a medium stiff texture.

CARBON FIBER: A very fine [Ø .000283] fiber of 95% pure carbon. Carbon Fiber has a tensile strength of 575 ksi, a tensile modulus of 35 msi, and an electrical resistivity of .00055 Ohms-in. This material is popular in light touch to non-contact grounding brushes due to its high conductivity. It is not recommended for uses with high flexural requirements since carbon fiber has low flex fatigue resistance and can break off rather easily.
NYLON-TYPE 6: Provides a good durable Nylon with good bend recovery, temperature stability and abrasion resistance at a low cost. It has a maximum short term use at 250°F (121°C) and a maximum continuous use at 200°F (93°C).
NYLON-TYPE 6.6: Top quality Nylon, medium-priced with higher stiffness, bend recovery, and abrasion resistance than type 6. It has the highest heat distortion temperature of the three Nylons. It has a maximum short term use at 356°F (180°C) and a maximum continuous use at 248°F (120°C).
NYLON-TYPE 6.12: Superior type Nylon used in applications calling for low water absorption. It has excellent bend recovery and abrasion resistance. This is the highest-grade nylon and it resists rot and mildew, while discouraging bacterial growth. Type 6.12 Nylon bristles are FDA approved and widely used for general purposes, in medical brushes, pharmaceutical brushes and food service brushes. It has a max short term use at 250°F (121°C) and a maximum continuous use at 200°F (93°C).
NYLON-ABRASIVE: A long wearing abrasive nylon filament impregnated with aluminum oxide or silicon carbide particles.
Aluminum Oxide is more impact resistant compared to silicon carbide and is less likely to fracture. It is preferred for finishing soft metals or other materials where a smooth finish is required. Aluminum oxide is generally available from 600 to 80 grit and diameter ranges from .012” to .040”.
Silicon Carbide is harder, sharper and more aggressive than aluminum oxide. It is preferred for finishing ferrous metals. Silicon carbide is generally available in 500 to 46 grit and diameter ranges from .018” to .080”.
NYLON-CONDUCTIVE: A type 6.6 Nylon with a 1 micron thick electrically conductive carbon coating suffused onto the outer surface is often used for anti-static bristle brush applications where a non-abrasive conductive fiber is needed. It is available in three standard diameters .010, .016, and .020 with other diameters available through special order. It has an average electrical resistance: 7.8 x10³ Ω/cm.
NYLON - HT: High Temp Nylon is type 6.6 Nylon with an additive that allows the fiber to resist oxidation at elevated temperatures. Standard Nylons have a high heat deflection temperature (softening temp) but are prone to oxidation embrittlement with extended exposures to high temperatures. Nylon HT is far less prone to heat oxidation and remains flexible much longer than standard Nylons. It is recommended for use in high temperature, high alkaline, high wear environments. It has a maximum short term use at 350°F (176°C) and a maximum continuous use at 302°C (150°C).
NYLON - STATIC DISSIPATIVE (aka Antistatic or Anti-static Nylon): A type 6.12 Nylon with a surface resistivity of 1x10 9 . Because the conductive element is not coated throughout the strand, it does not shed or slough and as a result, is clean room compatible. It is an excellent fiber to use for cleaning sensitive electronic circuitry as well as in explosive environments because it is non-sparking, it inhibits the generation of static charges, and can dissipate static charges on surfaces in a controlled manner.
PEEK: A durable thermoplastic that offers excellent chemical resistance, does not absorb moisture and is ideal for high heat and corrosive environments. PEEK provides excellent flexural and tensile strength and will work in continuous temperatures up to 480° F (250°C). It is a great alternative to Nylon for use in extreme chemical and heat applications.
POLYESTER PBT: A polymer that replaces horsehair. Its features of toughness and high temperature resistance resemble those of Nylon®, but Polyester is noted for its ability to recover without whip or slapping action, and it will not mat. Polyester has excellent resistance to all acids, alkalis, alcohols, gasoline, benzene and most cleaning solvents. It is a medium-priced filament that resists mildew, bacteria and fungus growth. Its maximum short term use at 320°F (160°C) and a maximum continuous use at 285°F (140°C).
POLYETHYLENE: Is a soft durable material suitable for applications where abrasion is to be avoided. These flexible bristles are very efficient for thorough washing and polishing of delicate fruits and vegetables. Polyethylene is ideal for soft, non-scratch wiping instead of a brushing action.
POLYPROPYLENE: Is a versatile, stiff, low cost filament used for a wide variety of applications. Polypropylene will not absorb moisture or odors and sheds dirt easily. It has excellent wet stiffness, abrasive tip cleaning action, is non-brittle, and is inert to most solvents, oil, acids, and chemicals. It is, in fact, one of the most chemically resistant synthetic filament materials available. It has a maximum short term use at 225°F (107°C) and a maximum continuous use at 175°F (79°C)
POLYSTYRENE: This material has replaced natural bristles for use where chemical resistance is needed. Its stiff aggressive properties make it ideal for utility brushes, coffee urn brushes, deck scrub brushes, floor and garage brushes. Polystyrene bristles wear longer, perform better, and yet carry a comparable price tag to natural bristles.
PTFE: Is a polymer commonly know by the brand name of Teflon®. This material is inert to most chemicals, resistant to strong mineral and oxidizing acids, along with alcohols, ketones, ethers, amines, esters, chlorinated compounds and common cleaning solvents. PTFE is very soft and has relatively low tensile strength but does maintain excellent property resilience up to 500° F (260°C) continuous.
PVC: Ply Vinyl Chloride is an economical material with a reasonable flex life, low friction resistance and no loss of stiffness in water.
THUNDERON®: Is an extremely soft acrylic fiber that has been chemically bonded with a layer of copper sulfide. This outer layer becomes a part of the host fiber itself, which precludes the 'flaking' problem experienced by other conductive fibers. The fiber diameter is available in two diameters: .07 mm (.0028") and .11 mm (.0043"). Its conductive layer is a super thin 300-1,000Å (angstroms). The material has an electrical specific resistance of 10¹-10²Ω/cm.

ALUMINUM: Is soft and non-corrosive. It has excellent conductivity but bends easily. Aluminum is recommended for special applications only.
BRASS: 260 alloys of Brass normally contain about 70% Copper & 30% Zinc. The bristle wire is the softest metal fiber available. The bristle wire comes either straight or crimped. It is used for light to medium cleaning and luster finishing. It has a maximum use at a temperature of 500°F (260°C).
CARBON STEEL: Is available both tempered and non-tempered as well as high carbon and low carbon versions, in a variety of sizes, straight or crimped. Carbon steel is a widely used metal fill material. It has excellent cutting ability and fatigue resistance for long brush life at a low cost. It is used for general-purpose cleaning, rust removal, deburring, edge blending, and roughing for adhesion. It has a maximum use at a temperature of 300°F (148°C).
NICKEL SILVER: This alloy nominally contains 65% Copper and 17% Nickel. The alloy’s electrical conductivity is about 6% that of copper. Because this alloy is very resistant to most chemicals, it is used in staple wires that hold the bristles in the block or handle. Nickel Silver is non-magnetic and stiffer and harder than brass or phosphor bronze.
PHOSPHOR BRONZE: C51000, phosphor bronze is made up of approx. 92% Copper, 4.7% Tin, 2% Phosphorous, 1.3% Zinc and trace amounts of lead. It is non-sparking and about 1/5 as conductive as Copper, stronger than brass [F73 Rockwell], and lasts longer. This material resists corrosion and fatigue due to flexing. It has a maximum use at a temperature of 500°F (260°C).
STAINLESS STEEL: Type 302/304/316 stainless steel for wet and no rust applications in a variety of diameters and comes either straight or crimped. It is highly corrosion and heat resistant and unlike carbon steel, stainless steel does not leave after-rust deposits when used on stainless steel, aluminum, and other high-strength alloys. However, once used on carbon steel it cannot be used on stainless steel or rusting can occur. This material is used in corrosive environments for general purpose cleaning, rust removal, deburring, edge blending, and roughing for adhesion. Stainless Steel is FDA approved and widely used in medical brushes, pharmaceutical brushes and food service brushes. It has a maximum use at a temperature of 800°F (426°C). Note: The austenitic 302/304/316 steel used in our brushes is cold worked [drawn] to achieve the desired tensile strength. This results in the stainless steel becoming somewhat magnetic. This magnetism is normal and is not an indication that the wire is not stainless steel.
TITANIUM (Ti): Commercially pure (CP) grade 1 or 2. Titanium is light weight at 40% lighter than stainless steel. Titanium has comparable strength and better bend recovery (returns to original position after bending) and has excellent corrosion resistance to water and chemicals due to a thin layer of titanium dioxide (TiO2) that forms on its surface. Titanium is non-magnetic and biocompatible (non-toxic and non-allergenic). Due to its high cost to process, titanium wire is usually reserved for uses in the aerospace and medical fields for cleaning or deburring other titanium parts. It has a maximum use at a temperature of 932°F (500°C).
OTHER WIRE MATERIAL: Other wire materials are available but may require special order and minimums such as: Inconel 600, Monel, Beryllium Copper, Copper Nickel, Nickel 200, Platinum and Tungsten.
