On 21 June 2018 ExxonMobil announced it had started production of hydrogenated hydrocarbon resin and halobutyl rubber at its integrated manufacturing complex in Singapore, the company’s largest integrated refining and petrochemical complex in the world. ExxonMobil’s new Escorez hydrogenated hydrocarbon resins plant will be the world’s largest with a capacity of 90,000 tonnes per year, and will meet long-term demand growth for hot-melt adhesives used in packaging or baby diapers. The new 140,000-tonnes-per-year butyl plant will produce premium halobutyl rubber used by manufacturers for tyres to better maintain inflation to improve fuel economy.
