The HT-SCE-3/8-2.0-4 is a heat-shrinkable identification marker sleeve designed for permanent marking in harsh environments. Fabricated from an irradiated, thermally-stabilised polyvinylidene compound, it offers a wide operating temperature range from -55°C to +225°C. This sleeve has a 2:1 shrink ratio, with a minimum supplied inside diameter of 9.53 mm (0.375 inches) that recovers to a maximum of 4.76 mm (0.188 inches). It exhibits excellent resistance to industrial cleaning solvents and fluids. Its low outgassing properties make it suitable for space and aerospace applications, while its high-temperature performance is ideal for industrial and electronic wire marking.
