DUWAI DWBS - Watertight Tube for Terminals and Crimp Splices
APPLICATIONS
The outer layer of DWBS heat shrinkable tubing is made of high density polyethylene, and the inner layer is coated with polyamide hot melt adhesive. It is used for heat shrinkable terminals and heat shrinkable crimp splices. The tough outer layer of the product can resist the possible damage caused by the terminal clamping operation, and the inner hot melt adhesive with a temperature resistance of 105˚C meets the requirements of high temperature environments, such as the automotive engine room. This tubing provides excellent resistance to abrasion, water and corrosion for complete insulation and electrical connection protection.
