HST-D 3X Type Heat-shrinkable Tube
HST-D 3x series is a semi-conducting thermal shrinkable bushing coated with a layer of thermosol inside. Its external layer consists of radiation cross-linked polythene, and its internal layer is the specially designed adhesive internal wall. When it is heated, the internal thermosol will shrink to the external wall and fill the clearance. When it is cooled,the thickness of double walls is very even and solid. It is widely used for the watertightness and air-tightness of wiring for electronic equipments, the sealing of wiring branch, rust protection of metal wires, and the remedy of wires and cables. It can prevent the polymer chains from loosening and falling, such as pool lamp, auto pipeline, and advanced lines.
HST-D Series Double-Wall Thermal Shrinkable Bushing
Overview
The WILLELE HST-D 3x series is a semi-conducting thermal shrinkable bushing featuring an internal layer of thermosol adhesive. The external layer is made of radiation cross-linked polyethylene, providing robust protection and sealing. Upon heating, the internal thermosol shrinks to fill any gaps, ensuring even and solid double-wall thickness upon cooling. This bushing is ideal for ensuring watertight and airtight seals in electronic equipment wiring, sealing wiring branches, rust protection of metal wires, and cable repairs.
