Heat shrink tubing is a versatile, radially expanded thermoplastic sleeve that contracts uniformly to a predetermined size when exposed to sufficient heat. This shrinkage creates a tight, durable layer that insulates wires, protects connections from abrasion, and bundles cables neatly, while forming an environmental seal that blocks moisture, dust, and chemicals. Its primary functions include providing high dielectric strength to prevent short circuits and electric shock, as well as safeguarding connections against corrosion, mechanical stress, and harsh operating conditions. PROSE supplies a comprehensive selection of heat shrink tubing in different shrink ratios (e.g., 2:1, 3:1, 4:1) and recovery temperatures.
Common applications span industries such as aerospace, automotive, telecommunications, and industrial machinery—wherever safe, insulated, and organized electrical connections are essential.
