Shin-Etsu Chemical developed the ST-OR Type heat-shrinkable silicone rubber tubing for busbar covering for the first time in the industry.

A busbar is a conductive metallic strip, typically made of copper or aluminum, and is used for power connection or distribution. Busbars have found wide-ranging applications and grown in demand for use not only in switchboards and control panels but also in electric vehicles (EVs) and hybrid vehicles (HEVs) more recently.

For being subjected to high currents and high voltages, busbars are protected with tape, tubing, or other insulating parts. In particular, busbars used in EVs and HEVs must endure even higher voltages and currents and thus require insulating parts that provide more advanced properties, including superior electrical insulation and heat resistance.

The ST-OR Type heat-shrinkable silicone rubber tubing for busbar covering, which Shin-Etsu Chemical has just developed, is a new product meeting these requirements.

By developing and suppling high-value-added silicone products based on its accumulated technological capabilities and know-how, Shin-Etsu Chemical helps customers solve their problems and contributes to the realization of a sustainable society.
