Product Description

Product Name: Double Wall Heat Shrink Tube

Our double-wall heat shrink tubing exemplifies innovation, crafted through a seamless co-extrusion of soft polyolefin and hot melt adhesive. The exterior, a robust polyolefin layer, ensures superior insulation, is halogen-free, and flame-retardant, while the interior adhesive layer excels in mechanical strain absorption and unrivaled sealing prowess. This makes it indispensable for the insulation and safeguarding of wires, cables, and connectors, especially where sealing and waterproofing are paramount. Its versatility shines across a spectrum of industries, from electronics to automotive and communications.

Key Features of Our Product
*Impressive Shrinkage Ratio: Choose between 3:1 or 4:1 for optimal fit
*Outstanding hot melt adhesive combined with a high shrinkage ratio ensures an impeccable seal
*Provides comprehensive sealing and insulation protection for electronic connections
*Facilitates easy insulation repair without necessitating connector removal
*Operates efficiently within a temperature range of -55ºC to 125ºC
*Begins shrinking at a temperature of 80ºC
*Achieves full shrinkage at a minimum temperature of 110ºC
