is a versatile heat shrinkable tubing for a variety of electrical and mechanical protection. It is constructed from an irradiated, cross-linked polyolefin which possesses superior mechanical and electrical properties along with thermal and chemical resistance. The thin wall construction allows for an effective bond when used as an insulation sleeve. It has a 2:1 shrink ratio, requiring only half the original diameter for complete shrinkage. Heat Shrinkable Sleeves 2:1 flexible 4.8/2.4 blue manufactured by HellermannTyton is a vinyl sleeving designed to provide electrical insulation and protection. It is constructed from an irradiated and cross-linked polyolefin, which provides superior mechanical and electrical properties along with thermal and chemical resistance. The sleeves have a 2:1 shrink ratio, which requires only half the original-sleeve diameter for complete shrinkage. Both the Heat Shrink Tubing and the Sleeve are used to bundle and protect wires, hoses, tubes, or electrical connections. They provide a clean, professional look and can also be used to create a weatherproof and waterproof seal.
