HUS-GR High Flame Retardant Adhesive-lined Heat Shrink Tubing
HUS-GR is a high flame-retardant, adhesive-lined, dual-wall heat shrink tubing. This PE tubing, which is extruded with flame-resistant EVA hot-melt adhesive, is manufactured in compliance with standard regulations. It can withstand mechanical strain and offers superior sealing capacity against water, corrosion, and dampness. Therefore, it is widely used in various wire harnesses, ship equipment wires, cables, and metal tubes.
