Frequently asked question (FAQ)

Question: What is the function of a heat shrink tube?: Answer: As its name suggests, a heat shrink tube shrinks when heated. An object will have its own characteristic shrinkage when its temperature reaches this stage. Heat shrink tubes are flame retardant, insulated, heat resistant and flexible. Such features determine their wide application. They are suitable for various harnesses, welding points, inductor insulation protection, and also can be used in various metal rods to prevent rust and corrosion.
Question: What are the advantages of this product?: Answer: ●The outer layer is made of polyolefin, and the inner layer is made of hot melt adhesive
●Excellent hot melt adhesive, excellent sealing performance and waterproof performance.
●Damaged insulation layer can be easily repaired without removing the connector
