FIT® Series, Heat Shrink Fabric

Heat shrink fabric, also known as heat shrink tubing, is a versatile material commonly used in electrical applications for insulation and protection purposes. It is typically made from polyolefin, polyester, or polyethylene, and it possesses the unique property of shrinking in size when exposed to heat. One of the primary uses of heat shrink fabric is as insulation material for connecting wires together. By sliding the heat shrink fabric over the connected wires, it can be heated, causing it to shrink and form a tight seal around the wires. This insulation helps to prevent electrical leakage and ensures a secure and reliable connection. In addition to wire insulation, heat shrink fabric has various other applications. It is commonly used for grouping wires together, providing a neat and organized appearance while offering protection against external elements. By enclosing multiple wires within a single heat shrink fabric tube, it helps to reduce the risk of tangling or damage. Heat shrink fabric also serves as a protective barrier, insulating items from mechanical wear. By covering vulnerable areas or components with heat shrink fabric, it shields them from abrasion, friction, and other forms of physical stress that could lead to damage. Another benefit of heat shrink fabric is its ability to suppress rattling noises. When applied to loose or vibrating components, it helps to dampen vibrations and minimize noise, resulting in a quieter operation. Heat shrink fabric is available in various sizes and specifications to accommodate different needs. The shrinking ratio refers to the reduction in size when heated, usually ranging from 2 to 1 or 3 to 1. This means that a heat shrink fabric with a 2 to 1 ratio will shrink to half its original diameter when heated. The length of heat shrink fabric can vary from as short as 1.772 inches (45.00 mm) to as long as 1640.4 feet (500.0 m). Supplied diameters determine the initial size of the heat shrink fabric before shrinking, typically ranging from 0.24 inches (6.1 mm) to 3.94 inches (100.0 mm). This range allows for flexibility in selecting the appropriate heat shrink fabric size for different wire or component diameters. In summary, heat shrink fabric is a versatile material used in electrical applications for insulation, protection, organization, and noise suppression. With its ability to shrink when heated, it provides a secure and seamless seal around wires, offers mechanical wear protection, and reduces rattling noises. Available in various shrinking ratios, lengths, and supplied diameters, heat shrink fabric can be customized to suit different requirements in wire management and other applications.
