Heat Shrinkable Sleeves

Heat shrinkable sleeves are polymer-based insulating tubes that shrink uniformly when heated, providing electrical insulation, mechanical protection, and environmental sealing for wires, cables, and joints. They are widely used in control panels, cable terminations, harnessing, and repair applications. Typical technical characteristics include high dielectric strength, defined shrink ratios (e.g., 2:1 or 3:1), flame-retardant and chemical-resistant properties, good flexibility, operating temperature stability, and availability in various sizes and colors for insulation, identification, and strain relief.
