FIT1053/64-BLACK-25 is a heat shrinkable tubing designed for wire and cable insulation, bundling, and protection applications. Constructed from cross-linked polyolefin material, this tubing features an approximate 2:1 shrink ratio with a minimum shrink temperature of 90°C and full recovery at 121°C. The tubing operates over a temperature range of -55 to 135°C and offers excellent mechanical properties including a minimum tensile strength of 1500 psi and elongation of 200%. It meets UL Standard 224 and CSA Standard 198 at 600V, as well as AMS-DTL-23053/5 specifications. This heat shrink tubing is ideal for electrical insulation, strain relief, and environmental protection in various industrial and electronic applications.
