Ube to close ammonia production
Ube Corporation has accelerated closure plans for its nitrogen products in Asia as part of its Vision 2030 plan. The company says that it aims to halt ammonia and related product production at its Ube City plant in Japan by March 2028, two years ahead of its previous schedule. Production of caprolactam and polyamide materials at the same plant will end by March 2027. Post-restructuring, the facility will prioritize specialty chemicals such as polyimides, separation membranes, ceramics, pharmaceuticals, and high-purity chemicals.
In Thailand, Ube will stop producing cyclohexanone, caprolactam, and ammonium sulphate, shutting down one of its two polyamide production lines. The site will shift focus to composite materials, polycarbonate diols, and elastomers, while Ube Fine Chemicals Asia will cease producing 1,6-hexanediol and 1,5-pentanediol.
