Product overview:
This heat shrink tubing for solar connectors has an environmentally friendly polyolefin (PE) outer layer and a specially designed hot melt adhesive inner layer. Once fully heat-shrinkable, it will not produce excess or bleed adhesive, effectively solving the common problems of conventional adhesive-backed heat-shrinkable tubing, such as adhesive leakage at high temperatures and adhesive layer aging or peeling off. The product provides superior insulation and water resistance, longer service life and a neat appearance when shrinked. It is widely used in photovoltaic, communication, power, outdoor wiring and industrial industries, providing reliable protection for a variety of cables and connectors.
