The SCT-NO.4-E2-0-STK is a black flame-retardant Heat Shrink Tubing made of irradiated modified polyolefin and offers 4:1 shrink ratio. It offers excellent physical, chemical and electrical properties. The tubing is designed to provide superior mechanical (strain relief), thermal and fluid-resistance performance in demanding environments. Widely used to provide insulation and strain relief of wire terminations and connections. Used for jacketing wire bundles and light-duty harnesses where superior abrasion resistance is a plus. Also used to identify and color-coded electrical connections and wire bundles.
