Sumika Electronic Materials is part of Sumitomo Chemical’s global network of compound semiconductor manufacturing facilities including: production facilities in Chiba, Japan and research and development in Tsukuba, Japan. The facility serves as the base of US operations and customer support for Sumitomo Chemical’s engineering plastics business. This includes a full line of Liquid Crystal Polymer (LCP) and Polyethersulfone (PES) resins. Super engineering plastics are high-performance resins that have excellent heat resistance, strength, chemical resistance, and processability. As materials that meet the needs for lighter and finer articles, super engineering plastics include liquid crystalline polymer, which is used in the manufacture of electrical and electronic products and is expanding into applications in the industry and automobile areas, and polyethersulfone, which in addition to electrical and electronics applications is also being used as a carbon fiber composite in aircraft, as a high-performance separation membrane material, and as a heat resistant coating. Sumitomo Chemical Advanced Technologies , a wholly owned subsidiary of Sumitomo Chemical, handles sales and distribution of Sumitomo Chemical’s IT-related and Energy & Functional chemicals in the NAFTA region as well as producing epitaxial wafers, grinding PES, and toll-manufacturing Penacolite in the US.
