星和電機 Company Profile

Technology of Light and Information "We will practice manufacturing with consideration for people and the environment." Seiwa Electric Co., Ltd. delivers peace of mind through technology.

Hoshia Electric has established itself as a top manufacturer in various fields, including information display systems such as road information boards, industrial lighting known for its waterproof and explosion-proof features under the name "Water Pearl," tunnel lighting that began with the full-scale installation in the Kanmon Tunnel, and resin products represented by "Cutting Duct." As a new business, we started an electromagnetic noise countermeasure (EMC) product business in 1997 to address electromagnetic noise issues arising from digital devices. In the LED business, we successfully developed a blue light-emitting diode in April 2002 and a white light-emitting diode in December of the same year. Based on these technologies, we are actively expanding our business in the field of LED lighting fixtures, ranging from roads and tunnels to industrial lighting. On March 9, 2018, Hoshia Electric Co., Ltd. was listed on the Tokyo Stock Exchange First Section. In April 2022, we transitioned to the Tokyo Stock Exchange Standard Market. Moving forward, we will continue to leverage our creative thinking and technological capabilities cultivated thus far to develop even more innovative products and strive for business expansion. Back to the roots of manufacturing "From the Kyoto to the world"

SGX01_1.jpg

Launched water-based dispersant "SGX" for carbon nanotubes.

  • PRODUCT

Carbon nanotubes (hereinafter referred to as CNT) are advanced materials discovered in Japan, characterized by their lightweight, high strength, and excellent elasticity and conductivity, which are being utilized in industrial products. However, CNTs have a tendency to aggregate, making it difficult to achieve uniform dispersion in resins and liquids. Achieving stable and uniform dispersion is a challenge in order to fully realize their original performance. Our company has been developing CNT dispersants based on research results from universities and companies, utilizing our unique polysaccharide extraction technology. We have now completed the technological development for commercialization and will begin manufacturing and sales.
