HUS-DW Non-Squeezeout Dual Wall Heat Shrink Tube

Product Overview：

This solar connector heat shrink tube features an environmentally friendly polyolefin (PE) outer layer and a specially formulated hot melt adhesive inner layer. It produces no adhesive overflow or flow after full heat shrinking, effectively resolving common issues with conventional adhesive-lined heat shrink tubes such as adhesive bleed at high temperatures and adhesive layer aging or peeling.The product offers excellent insulation and waterproof sealing performance, a longer service life, and a neat appearance after shrinking. It is widely used in photovoltaic, communication, power, outdoor wiring harness and industrial applications, providing reliable protection for various cables and connectors.
