![]() This tape is puncture resistant, conformable, and has good electrical qualities. Polyethylene teraphthalate (PET)/polyester products use a PET or polyester backing in the form of tape, film or laminate. Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. Fluoropolymers are also used in applications where the material handled must not stick to the belt, fabric or laminate. Fluoropolymer coatings are used in applications that require superior chemical resistance, good dielectric properties, and water and stain repellent characteristics. This includes synthetic rubbers.įluoropolymer films, layers or coatings consist of plastics such as polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF). Many types will bond to itself to create a solid, water-tight mass. Rubber-backed cable tape provides excellent insulation for wires up to 600V. There are two general categories of plastics: thermoplastics and thermosets. Plastic products incorporate one or more plastic layers, or consist of plastic film or sheets that can be clear or colored, printed or plain, single-layered or multilayered, and combined with materials such as aluminum and paper. They can fill gaps and are ideal for metal or metal-plated surfaces. These compressible, electrical tapes offer good electrical conductivity with cushioning/recovery attributes. These shielding tapes are meant for applications needing point-to-point electrical contact, grounding, and static charge draining.Īdhesive-coated polyolefin foams include an adhesive that is protected by a liner in the form of a tape, film or laminate. Metal foils have aluminum, aluminum reinforced, or lead backings. They can also be used for wave solder masking. Polyimide films have moderate heat resistance, can be applied at low temperatures, and are relatively thin. These are similar to cloth carriers, but are reinforced with glass or fiberglass particles to enhance heat resistance to over 300° F.Īcrylic films can be transparent and UV resistant. This is the most common electrical tape carrier.Ĭloth materials like cotton can be used as the carrier material to improve tensile strength, heat resistance, and electrical resistance. When used for electrical insulation, the PVC must be plasticized to enhance its insulating properties. It has similar properties when compared to rubber, but is less expensive and more chemically resistant. PVC-backed electric tapes can be applied as a tape, film, or laminate. ConfigurationsĬable and electrical tape manufacturers can use whatever permutation of carrier and adhesive they desire for the marketplace they serve. Products approved by standards organizations are branded with the organization's mark and ensure a superior product. The manufacturing process for shipping tape is identical.Ĭable and electrical tapes are usually evaluated for professional quality and safety by standards organizations like Underwriters Laboratories (UL) or the Canadian Standards Association (CSA). After cooling, the tapes are cut into proper-width rolls and sent for distribution. Like other adhesive and industrial tapes, the manufacturing process involves large rolls of backing that are coated with an adhesive. The final turn should have reduced tension. ![]() This consists of overlaying each turn of the tape by half of its width, as represented below. Electrical tape owes its versatility to its good tensile strength, UV-resistance, lack of residue upon removal, and that it can be easily torn by hand.įor most jobs, diagonal, half-lapping of the tape is considered the optimal application method. Some tapes may by self-adhering, meaning no tacky adhesive is used but the tape sticks to itself by the use of a high-friction carrier. Essentially, a type of adhesive is applied to a carrier or backing that provides electrical insulation. Electric tapes come in many colors and materials, but black, vinyl tape has become the consumer standard.Įlectrical tapes operate differently depending upon the materials of construction. Cable and electrical tapes are a variety of pressure-adhering adhesive tape specifically designed to wrap, shield, mask, mark, or insulate types of electrical cables, wiring harnesses, electric components, or circuit boards.
