Product Description

Double Wall Heat Shrink Tube

Double-wall heat shrink tubing, crafted from soft polyolefin and hot melt adhesive co-extrusion, is a marvel in insulation technology. The polyolefin outer layer stands as an insulating guardian, free from halogens and resistant to flames. Meanwhile, the inner hot melt adhesive layer acts as a robust buffer against mechanical strain, offering unparalleled sealing prowess. This exceptional tubing is the go-to choice for wire and cable insulation protection, providing the necessary sealing, waterproofing, and moisture-proof capabilities. Perfectly adaptable to industries spanning electronics, automobiles, and communications.

Product Features
*Shrinkage ratio: 3:1 or 4:1
*The superior combination of hot melt adhesive and high shrinkage ratio ensures remarkable sealing properties
*Achieves impeccable sealing and insulation protection for electronic connection purposes
*Effortlessly repair damaged insulation layers without needing to remove the connector
*Operates reliably within a continuous use temperature range of -55ºC to 125ºC
