Custom Block Brushes
Block brushes encompass any type of brush bristle inserted into any type of block. Brush bristle may be stiff, like steel wire brushes, or soft, like nylon brushes for brooms. Bristle sizes can be large or fine. Blocks may be made of plastic, metal or wood. Some examples of Block brushes are shown in the picture. Common names for these types of brushes include push brooms and scrub brushes. The uses for such a brush are truly endless. We at Gordon Brush can work with any block or bristle material listed in the "Materials" section to make the brush that suits your application.
Block brushes, often what people think of as standard brushes, are brushes made from a block of backing material with bristles inserted into it. The design of the block can vary significantly, from hand held, like a toothbrush to a push broom to a circular brush used by street sweeping machines. The concept of each brush is the same. A brush block, or back, is manufactured through the drilling of holes and insertion of bristle tufts into those holes. The brush back can be made from a wide variety of materials, as can the bristle or fill material. Regardless of the materials, block brushes are used for many purposes, some of which are mentioned below.

Block Brush Applications
General applications for any brush are: Applying, Pushing, Removing, Cleaning, Spreading, or acting as a Barrier.
Specific Uses for Block Brushes Include:
Block Brush Sizes and Styles
The size of a Block brush reflects the measurement of the block's length, width and height. The block can be as small as 1/4" (6.4mm) in length, and literally as long as you need. It can be as small as 1/4" (6.4mm) in width, or as large as 6" (152mm). The height or thickness must be at least 3/16" (4.2mm) for conventional staple set construction. For an Anchor Set brush (like your ordinary toothbrush), the height may be as small as 1/8" (3.2mm), with no maximum restriction. The style of the block can be square, rectangle, triangular, round, or any combination thereof. The trim length on any of these brushes can range from as short as 1/16" (1.6mm) to as long as 6" (152mm) or even longer. These measurements hold true for any bristle material.
Block Brush Fill Materials
The fill material used in the brush can be natural hairs, and synthetic/polymer, plant, and metal fibers. The use of the brush will determine the types of fill material and block material to be used. For example, natural bristle, static dissipative nylon, or conductive materials is sometimes used where static generation is a problem. Synthetic materials are often used for general purpose cleaning, and some are chemical resistant and others are used in high temperature environments. Metal materials are used for heavy duty cleaning, and cleaning other metal surfaces.
General Notes on Block Brushes
To stiffen a brush, shorten the trim length, use a larger diameter bristle, or increase the diameter of the tuft. To lengthen the life of a brush, use the softest fill material appropriate for the job. If you want maximum bristle retention, consider purchasing a hand laced brush. With this construction, the bristles are literally hand tied into the brush back with stainless steel wire. Hand tied brushes works well when the brush will be submerged in liquids for long periods of time, or exposed to extreme temperature variations.
