SI Group has announced its plans to cease manufacturing operations at its alkylphenol manufacturing facility at Jurong Island, Singapore, in 2H 2025. It will continue supplying alkylphenols from its other sites in Europe and the Americas.

The facility opened in 2006 to supply alkylphenols to the Asia-Pacific market and produce antioxidants. The company blamed “substantial changes in the antioxidant value chain in the region in recent years, paired with high costs in Singapore”.

Texas-based SI Group has concluded a long-term supply partnership with Liaoning Dingjide Petrochemical of Shanghai, a manufacturer of additives and other speciality chemicals. Dingjide will manufacture certain unnamed SI antioxidant products at its site and SI will consequently close its operations at Jinshan on 31 July and is now seeking a buyer immediately.
