The global market place is increasingly demanding safe process oils to reduce the environmental impact of tires. The replacement of classified distillate aromatic extracts by non-carcinogenic MES, TDAE, or naphthenic process oils will reduce the PAH emissions from tires by more than 98%, Rubber tests back-to-back with DAE with carbon black and silica filled vulcanisates show a slight shift in wet grip performance and an improvement in rolling resistance for all alternative oils. MES type oils from different crude oils and refineries are fully interchangeable in rubber and compound formulations. MES have already been made on commercial scales in various parts of the world.
