In the field of automobile manufacturing and maintenance, the safe and stable operation of wiring harnesses is of vital importance. Once there is a problem with the wiring harness, such as insulation failure, moisture short circuit, etc., it will seriously affect the performance and safety of the car. The SBRS-VBK series semi-rigid double-wall heat shrink tubing for automotive wiring harnesses produced by Volsun can effectively solve these problems with its excellent performance.

This dual wall heat shrink tubing is co-extruded from semi-rigid, flame-retardant polyolefin and hot melt adhesive. The outer layer of polyolefin provides insulation, corrosion resistance, and wear resistance, with a tensile strength of ≥10.4MPa, which can effectively resist external friction and erosion. The inner layer of hot melt adhesive has a low melting point, waterproof sealing and mechanical strain buffering properties. In the complex operating environment of the car, it can tightly wrap the wiring harness to prevent water vapor and dust from entering, and can also alleviate the impact of vibration on the line.

Moreover, this heat shrink tubing has a high shrinkage ratio of up to 4:1, and a shrinking temperature of 125℃~200℃. It can fit closely to different specifications of wire harnesses, from Φ4.0mm to Φ17.78mm, to ensure stable installation. The operating temperature range is -40℃~125℃, and it can function stably in both severe cold and hot weather.

Volsun has always insisted on safe and environmentally friendly production, and its heat shrink tubing products meet RoHS environmental standards. At the same time, the breakdown strength of the polyolefin outer layer is ≥15kV/mm, and the volume resistivity is ≥10¹⁴Ω・cm. It has excellent insulation performance, effectively prevents leakage, and ensures the safety of the automotive electrical system. It is mainly used for waterproof sealing and fixing of automotive wiring harness branches and repair of wires and cables. In high temperature, humid and frequently vibrating environments such as the engine compartment of a car, it can reliably protect the wiring harness, avoid car failures caused by line problems, and greatly improve the reliability and durability of the car.
