Mitsubishi Plastics, world’s leading manufacturer of alumina fibers for vehicles, will increase the production capacity by 10% with an investment of about two billion yen. The company has 80% share in the global market of alumina fibers used for the protection of catalysts to purify gas emissions. Its alumina fiber is a high performance material with high heat resistance that can maintain thermal insulation properties and cushioning characteristics even at such a high temperature as higher than 1,600 degrees centigrade. It is processed to be sheet-like and used to wrap the catalyst.
With the investment, Mitsubishi’s annual production capacity of alumina fibers will increase to 3,000 tons within the year. The Ministry of Economy, Trade and Industry will subsidize part of the investment. The regulations on nitrogen oxide contained in exhaust fumes are growing more stringent in China and Europe. In addition, construction machinery will be subject to gas emission regulations in the near future. The company decided to make an investment to prepare for the rapid spread of stringent emission control worldwide.
