ESSEN, Germany - Evonik Industries has produced AEROSIL® in Yokkaichi, Japan, for 40 years. The first shipment of AEROSIL 200 left the Yokkaichi production facility in November 1968. Nippon Aerosil Co. Ltd. (NAC), operator of the site, became one of the most successful joint ventures in the portfolio of its founders, Mitsubishi and Degussa, now Evonik.
The plant in Yokkaichi, which is about 400 kilometers west of Tokyo, initially supplied the local Japanese market but has gradually grown into a supplier for the entire region. Today, Yokkaichi comprises not only the largest and most tradition-steeped production facility for fumed silica in Japan, but in all of Asia. At the same time, it is also the second-largest production site for AEROSIL at Evonik Industries. In addition to production, Yokkaichi is also a regional center for R&D and technical service for fumed silica.
More than 50 different products are manufactured in Yokkaichi, including products for applications in silicon, adhesives, paints and coatings, plastics, and toners.
