Luminous Heat Shrink Tube Review
2026-05-30
The luminous heat-shrinkable tube is made of polyethylene with the addition of a special luminous powder, and is available in two types: single-walled with a shrinkage ratio of 2:1 and double-walled with an adhesive layer of 3:1. Withstands temperatures up to 125℃ and rated voltage 600V, RoHS compliant. It has electrical insulation, corrosion resistance and glow-in-the-dark ability, used for fishing gear, cables, tool handles and boat parts for protection and night marking.
According to market statistics, green modifications account for over 80% of all sales. Red and blue options have an increased cost of raw materials and glow weaker, so they are produced only according to individual orders without a constant warehouse stock. The 2:1 single wall tube is suitable for wrapping rod handles and cable markings, while the double wall adhesive tube heats to melt the inner adhesive layer to provide a water seal, ideal for underwater fishing gear parts. The optimal shrinkage temperature is from 110℃ to 130℃; prolonged heating above 180℃ destroys the luminous powder and permanently deprives the product of its glow.
The development of the fishing industry is the main consumption direction of luminous heat shrink tube. Diversified performance requirements continuously improve product performance and help luminous heat shrink tube increase its market share in pipe products。
