The sheathing tape is made of environmentally friendly cross-linked polyolefin material and hot-melt adhesive, featuring softness and insulation, corrosion resistance, and other functions. It is mainly used as an outer protective layer for cables in the power, communication, automotive, marine, aircraft manufacturing, and other industries to prevent mechanical damage, such as repairing damaged surfaces caused by organic solvent corrosion, heat-shrinkable cable intermediate connectors, waterproof sealing treatment of sheath ports, protection of live bare conductors passing through trees, prevention of icicle short circuits when crossing tunnels, pipeline corrosion prevention and sealing, insulation and sealing protection of switchgear and power station busbar bars, and other places requiring insulation and sealing.
