STAPLE SET INFORMATION

Staple-Set brushes are brushes consisting of discrete tufts of bristles or filaments inserted into holes in a block of wood, plastic, rubber, or leather. The tuft is held in the hole by a metal staple or anchor. Staple-set brushes are used to clean, scrub, dust, agitate, apply a material, remove a material, or transport/support. The staple-set brush is the most versatile and is found in more configurations than any other brush. There is almost no limit to the type of block material, bristle material, or brush tuft pattern.

Easily prototyped Tuft sizes from .093 to .250 in. diameter Small - Large production lots Innumerable shapes and sizes Production can be manual prototype or CNC Low set-up costs Minimal Tooling costs

All bristle materials: Animal Hair, Vegetable fiber, Plastics, and Metal

 


METAL STRIP INFORMATION

Strip brushes are formed by folding a metal strip over bristle material, with a wire inside the fold of the bristle running the length of the brush to lock the bristle into the formed channel. The resulting strip can be formed in long lengths (pretty much limited in length by how long a strip the trucking companies can move). The strip can also be shaped and formed into cups, triangles, disks, rings, and coils. Differing widths of strips can be used to give very thin strips, or thick strips-- from about 1/8" thick,to about 7/16" thick.

Besides being easily formed into a variety of shapes, the straight strip can be inserted into various configurations of aluminum extrusions to aid in mounting the brush.

Bristle materials can be any of the standard plastics, metals like brass or stainless steel, and natural bristles like vegetable fiber or animal hairs. The metal channels can be galvanized steel, stainless steel, brass, or aluminum.

 


WHEEL BRUSH INFORMATION

These brushes are used primarily to remove burrs and aid in surface finishing. The fill is usually stainless steel or carbon, but can also include other metal fills or abrassive nylons. Arbor hole, trim length, and brush diameter vary depending on the intended use of the brush. The fill material can also be crimped, twisted, knotted, and coated for the specific needs of every manufacturing problem.


TWISTED IN WIRE INFORMATION

Primarily used for cleaning and dressing inside cylindrical surfaces. The fill material of a twisted-in-wire is held between two if four stem wires. As the wire is twisted the brush takes on a spiral shape and the fill radiated in all directions from the stem.They vary in diameter from .020" to 4" in diameter. Lengths of the brush can be custom made from 1' to 4 feet. Fill material is somewhat limited by the size of the diameter of the core wire but is very flexible.

Fill material will vary depending on the stem wire diameter. Typically run from .003 to .014 in diameter. Wire could be carbon steel, Stainless, brass, bronze. Natural fill could be tampico, horsehair, China bristle. Synthetics include polypropylene, nylon, abrasive nylons, polyethylene and polystyrene.

 


FERRULE INFORMATION
Paint & Artist Brushes

The most recognized of brushes types. These include paint brushes, artist brushes, glue brushes, chip and oil as well as many more applicator of liquid and viscous solutions.

Fill material generally include natural and synthetic fibers. The fibers are inserted into a ferrule and set with a binding resin. The ferrule is attached to a handle or other material depending on its application. In some applications a plug is used depending on the application and density required.

 


FILL MATERIAL INFORMATION

Vegetable Fiber,
Animal Hair, Metal Wire, Synthetic Fibers

 


Vegetable Fills:

Tampico: Produced in Mexico from the stalk of the Agave plant. It has a soft to medium texture and is off-white in color. It is often dyed and blended to give various effects. has naturally occurring calcium oxalate crystals contained within the fiber which gives it a lightly abrasive characteristic similar to Bon-Ami. (Diatomaceous Earth) Carries up to 65% of its weight in water.

Biodegradability: Excellent

Anti-Static characteristics: Its ability to absorb water makes Tampico a good to excellent anti-static.

Specific Gravity: 1.38

Chemical Resistance: Excellent resistance to petrochemical solvents. Resistant to boiling soaps and strong alkalis, as long as immersion is complete. Boiling caustic sodas cause degradation in the presents of air. Attacked by acids. Weak bleaches are acceptable at low temperatures, but degradation occurs at high temperatures.

Wet Strength: Becomes somewhat limp in the presence of water.

Patent Fiber: A select grade of polished tampico, usually dyed black and blended with horsehair. Is slightly stiffer that undyed tampico, and used in floor brushes, truck wash brushes, and other brushes where a finer quality is needed.

Union Fiber: A blend of white tampico and palmyra fiber to give good scrubbing action and improved water resistance. use in floor polishing brushes, bowl scrubs.

Palmyra: Produced from the base of the leaf stalks of the India Palmyra palm. Medium stiff to stiff. natural color is light to dark brown. Stiffer than Tampico. used in scrub brushes, garage brooms and deck scrubs. There are various grades of Palmyra.

Biodegradability: Excellent

Specific Gravity: 1.14

Chemical Resistance: Excellent resistance to petrochemical solvent. Resistant to boiling soaps and strong alkalis, as long as immersion is complete. Boiling caustic sodas cause degradation in the presents of air. Attacked by acids. Weak bleaches are acceptable at low temperatures, but degradation occurs at high temperatures. Use on oily shop floors will show acceleration wear of the fiber.

Wet Strength: Absorbs water, but not as much as Tampico, so it retains most its strength when wet.

Types of Palmyra:
Palmyra fiber, undyed
: available in medium stiff, prime stiff, and extra prime stiff. Cuts are available up to 20 inches.
Bassine: Dyed Palmyra. Usually dark brown, gray or black. Grades and lengths of bassine the same as undyed palmyra, though stiffness is usually a bit higher than undyed. More resistant to water than undyed Palmyra.
Palmyra Stalks: Made from the fibs of the palmyra leaf. This is a stiff fiber, used in street brooms, and as a center filler for more aggressive corn brooms.

Sherbro Pissava: Mostly produced in Brazil. It is a stiff, aggressive fiber used in street brooms, Yard and barn brushes, railroad brooms and heavy construction broom. Available in lengths up to 42 inches.

Biodegradability: Excellent

Specific Gravity: 1.03

Chemical Resistance: Excellent resistance to petrochemical solvent. Resistant to boiling soaps and strong alkalis, as long as immersion is complete. Boiling caustic sodas cause degradation in the presents of air. Attacked by acids. Weak bleaches are acceptable at low temperatures, but degradation occurs at high temperatures.

Wet Strength: retains most of its stiffness in presents of water.

Coco fiber: Most popular in Europe, Japan and other parts of the world than in America. It is low cost, and light-weight. Used in light sweeping applications, It is softer and aborts less water than tampico. color is reddish brown, but is often dyed black. Available in cut lengths up to 9 inches.

Calabar Pissava: Produced in Nigeria, but the stiffest grade is no longer exported.

Madagascar Fiber: A fine quality fiber production in Madagascar, but only small quantities are exported, usually for specialist brushes in Europe.

Kitool Fiber: A palm fiber produced in Sri Lanka. Very fine quality, but no longer exported.

Gumati Fiber (Arenga): A palm fiber produced in Indonesia. Strong, gray-black. Still used in Europe. Available in lengths up to 46 inches  in length.

Palmetto Fiber: A stiff palm leaf fiber. No longer produced for export. Was used in corn brooms to stiffen the action.

Split Bamboo Cane: Used in the Far East for stiff brooms, but replaced palmyra stalks in the US and Europe.

 


Animal Hair

Boar Bristle: Relatively scarce and fairly expensive. This hair has characteristics which make it unique and very suitable to certain application. Each bristle is tapered from butt to tip, which gives it great resilience. The tip of each is split into two or more branches called flags.

In a floor broom, these flags penetrate into cracks, remove the finest dust. In a paint brush, it increased the ability of the brush to smoothly apply paint to a surface, which makes it an unexcelled fiber for use with oil based paints, It doesn't perform well with water based paints, as it absorbs a great deal of water, which caused it to swell and load, while at the came time loses its snap. Boar bristle is naturally brown, black or gray, but is often found bleached to a unique blonde color. The bristle is produced almost exclusive in China, hence the other name: China Bristle.

There are four main grades of boar bristle. From coarsest to finest: Chunking, Hangkow, Tsentsing, Tsintow.

Biodegradability: Fair

Specific Gravity: (Average) 1.31

Chemical Resistance: Very Resistant to petrochemical solvent and non-oxidizing acids. Attacked by strong alkali solutions, especially at elevated temperatures.

Horsehair: Produced in Canada, U.S., Argentina, Australia, and other countries. Tail hair is stiffer and more resilient than Mane hair. Body hair is also used, but mostly for cosmetic brushes. Horsehair is a medium cost material. It is most often black or gray in color, and is very durable, The soft-slight stiff texture gives good performance in floor brushes and counter dusters. Also used in window brushed, fountain brushes, and radiator brushes. Horsehair can also be flagged mechanically for better dust carrying performance.

Biodegradability: Fair

Specific Gravity: (Average) 1.26

Chemical Reaction: Very Resistant to petrochemical solvents and non-oxidizing acids. Attacked by strong alkali solutions, especially at elevated temperatures.

Goat Hair: Generally used in miniatures polishing brushes for the jewelry and dental trades. The soft fine but durable material  is also great for make up brushes.

Ox and Sable Hair: Use for artist and other fine marking brushes. It is naturally tapered and fine.

 


Metal Wire

Wire - Steel Low Carbon: Soft steel for light material removal and for surface and finishing of soft materials. Color is silvery gray, and will rust easily. Low-carbon steel is magnetic.

Hard-Drawn wire: Gives a more aggressive brushing action than low-carbon steel.

Wire - Hi-Carbon Tempered Stainless type: Generally resistant to corrosion and elevated temperatures. Stainless steels are alloys containing between 12 and 30% chromium. Other metals are added depending on type for additional corrosion resistance and varieties of mechanical properties.

There are two main series of stainless steel. The 300 or austenitic series, and the 400 or martensitic series.

The 300 series are chrome.nickel (and some also contain other metals) carbon steels. They exhibit the highest resistance to corrosion to all the stainless steels, and have fine mechanical properties. They cannot be hardened by heat treating, yet great tensile strength and hardness are obtained by cold-working. These steels are not-magnetic normally, but become slightly magnetic as they are drawn and crimped.

The 400 series contain chrome, but no nickel. They can be hardened by heat-treating and rapid quenching (cooling) in oil or air. This series is magnetic and will rust, though more slowly than carbon or low carbon steel.

Type 302 (or 18-8): A general purpose type with good corrosion resistance. Contains 17-19% chrome, 8-10% nickel, 0.15% max carbon.

Type 304: A general purpose type, it is a low carbon variation of type 302. contains 18-20% chrome, 8-10% nickel, 0.08% max. carbon. Normally, 304 is the best cost effective stainless steel.

Type 316: Has superior corrosion resistance to other stainless steels. Cost is roughly 50% higher that type 304. Contains 16-18% chrome, 10-14% nickel, 0.08% max. carbon, and also contains2-3% molybdenum. the molybdenum improves general corrosion and pitting resistance, and higher temperature strength than type 304.

Type 321: Is a stabilized steel permitting use at temperatures in the 800-1500 degree range. it contains 17-19% chrome, 9-12% nickel, 0.08% max, carbon and also contains 5% or more titanium. the cost is 2 to 5 times that of type 304.

Type 420: Lowest cost, heat treatable, general purpose stainless steel, used where corrosion resistance is not a high priority. it is magnetic. It contains 12-14% chrome, no nickel, and 0.15 max carbon.

Type 430: Most popular of the chromium types. contains good corrosion and heat resistance. It is magnetic and will rust. it contains 14-18% chrome, no nickel, and 0.12% max carbon.

Synthetics

Acrylic: Available in a variety of colors, sizes from .0015" to .003 inches diameters. The largest uses in the brush industry is for static discharge applications.

Polypropylene: Very popular all purpose fiber due to its low cost, long life and resistance to acids and alkalis. Sizes are .0055 to .060 inches diameters in both straight and crimped.

Polyethylene: Well suited for wet application and available in .008 to .044 inches diameters. Flagable tips.

Nylon: Useful for scrubbing and cleaning applications because of its resistance to acids and alkalis. Available in .06 to .085 inches diameter.

Abrasive Nylons: Use for surfacing finishing, deburring, edge radiusing and decorative finishing on steel, aluminum, stainless, brass, plastic. The nylon has an extrudes abrasive grain impregnated through out. This allows the same cutting action through out the life of the brush.
