Metal-backed Brush Construction

We’re all familiar with the common uses for brush: cleaning and sealing gaps to prevent air infiltration around doors and windows. But, the wide variety of materials and construction variations provide brush with unique properties that make it ideal in applications where other materials wear out quickly or just don’t perform as well. Some of the unique benefits brush can provide, include:

• Seals effectively around moving parts
• Provides an effective seal with virtually no friction
• Seals out light, sound, vapors, sprays, dust and other contaminants
• Prevents air infiltration by as much as 98.5%
• Works in low and high temperatures
• Resistant to chemical agent
• Durable – works for millions of cycles

Flexible Brush Construction

In many applications, brush is simply the best solution.
For example, when closing gaps between two moving surfaces, conventional solid seals often breakdown quickly from friction and abrasion and can exert excessive drag and wear on parts. Sealeze brushes are pliable and highly effective at closing gaps between uneven surfaces to keep out dust, dirt and other contaminants while allowing a full range of motion for moving parts. Brush can be the best solution to many other problems, as well. Other examples include: shielding in paint booths and machine tools, guiding product on conveyor systems, closing gaps between moving surfaces, static dissipation, augers for moving delicate product, closing large gaps in commercial buildings (airplane hanger doors, for example) and much, much more.
 
The choices are almost infinite.
The unique properties of brush come from the almost infinite variety of materials that can make up its three basic parts: core wire, metal backing or channel and filament. Channel materials can range in size from small (less than 0.095 inch wide) to large (more than 0.5 inch wide). As channel size increases, physical strength is greater as is the ability to make brush with filament materials that are larger in diameter, longer and to put more filament material in the brush to make it denser.

An almost endless variety of filament materials, each with its own set of properties, can be used to produce brush with different characteristics. Synthetic filaments, such as nylon, polypropylene and polyester, each have different properties of stiffness, absorption and resistance to heat/cold and chemical agents and are available in a wide range of filament diameters. The same can be said for metal filaments and natural filaments such as hair and plant fiber. All of these fibers can be trimmed to various lengths to further provide variation in stiffness and other properties. And, brush can be made with more or less fill to provide more or less density, more or less stiffness, etc.
 
In addition to the almost infinite variations in size and physical properties, brush can be formed into almost any shape – spirals, coils, arcs, rectangles, circles, etc.
 
A solution that lasts.
The durability of brush in applications where moving parts are involved is unsurpassed. Independent laboratory testing has shown Sealeze nylon stock brush to stand up to 2,000,000 cycles (opening and closing) without excessive wear or degradation.
