The RNF-150-1/4-0-SP is a black highly flame-retardant Heat Shrink Tubing made of flexible cross-linked fluoropolymer and offers 2:1 shrink ratio, approximately 40 percent thinner walls than most general purpose polyolefin tubing, can be used for jacketing and bundling of wires to form light-duty harnesses, especially where a low profile, abrasion resistance and flexibility are needed. It can also be used to provide insulation and strain relief of electrical connections and wire terminations, identification of wires and packaging of components.
