Nano-Composite Heat-Shrinkable Tubing

摘要

Sumitube is heat-shrinkable tubing that is widely used in the electronics, automotive, aerospace and other industries for insulation protection and waterproofing of electric wire terminals or harnesses, bundling electric wires, insulation protection of electronic parts or components, and corrosion protection of metal pipes. Recently, thinner wall heat-shrinkable tubing is required for the purpose of saving space and weight, especially for applications involving electronic parts and components. However, thinner wall tubing generally causes difficulty in covering electronic parts due to its lack of rigidity. Therefore, we have developed a very thin wall heat-shrinkable tubing by applying polymer nano-composite technology (nano-meter size fillers dispersed in polymer), which has sufficient rigidity for easy handling, positioning, and installation over electronic parts or components and shrinks in less time, at a lower temperature.
