SDK Receives Award for Development of Halogen-Free Insulating Resin for Electronics

Showa Denko K.K. (SDK) has received Tsukuba Foundation for Chemical and Bio-Technology’s award for the company’s development of innovative insulating resin based on a clean oxidation technology using hydrogen peroxide. The National Institute of Advanced Industrial Science and Technology (AIST) conducted the development jointly with SDK.

This technology will enable the production of high-performance materials for electronics without using chlorine compounds while restricting emission of wastes.

While insulating resins are used to coat and protect a wide variety of electronic circuits, including those for large-sized LCD panels and mobile phones, there has been the problem of short circuit resulting from chlorine compounds contained in the resins. Specifically, with the lapse of time, those resins generate hydrogen chloride gas, degrading their insulation performance. When their heat resistance is raised to prevent the problem, resin flexibility declines, putting limitations on the scope of applications.

SDK and AIST have developed innovative resin with excellent long-range insulation performance (more than 100 times that of the conventional resin) and high flexibility by establishing a resin manufacturing process that uses hydrogen peroxide instead of chlorine compounds and adopting a new curing agent.

Furthermore, there is no emission of environmental pollutants during the production. SDK will distribute samples of the newly developed resin to the electronics industry to help develop closely wired electronic circuits with high long-range insulation performance and flexibility.

Tsukuba Foundation for Chemical and Bio-Technology aims to contribute to industrial development by supporting R&D efforts in chemistry and biotechnology and encouraging cooperation between the industry and governmental agencies. The foundation gives awards every year for remarkable R&D work in the area of chemistry and biotechnology.

SDK and AIST have received the award for this year in view of the great potential of the new resin technology. The commendation ceremony, together with memorial speeches, will be held at Tsukuba City on May 20.
