Sumitomo Chemical plans to construct a new production facility for polyethersulfone (PES) engineering plastic at its Chiba Works in Ichihara City, Chiba, Japan. The new facility will have a production capacity of 3,000 tonnes per year. Commercial production start-up is slated for in 2018. When the facility becomes fully operational, Sumitomo Chemical’s total production capacity of PES, combined with the existing facility in its Ehime Works in Niihama, Ehime, will grow two-fold. PES is a thermoplastic resin with excellent properties in terms of its heat resistance, dimensional stability, flame resistance, and hot water resistance.
