SI Group Raises Prices Across Full Product Portfolio Effective October 2026

SI Group, a performance additives, process solutions and chemical intermediates producer, has announced a price increase across its entire product portfolio. The increase takes effect October 1, 2026, or as existing contracts allow. The company says the move supports product quality, reliable supply and reinvestment, citing ongoing geopolitical conflict in the Middle East that is disrupting refining capacity, raw materials, logistics and energy markets.

Key facts

Market context

Performance additives, process solutions and chemical intermediates such as those SI Group makes are used to improve the behavior and durability of other materials rather than being sold as end products. Antioxidants and stabilizers protect polymers during processing and service, while resins and modifiers tune the properties of rubber, adhesives and coatings. Demand therefore follows the health of downstream sectors including plastics, tires and rubber goods, adhesives, fuels, lubricants, coatings and oilfield operations. When a producer raises prices across an entire range, buyers typically look for the reasons behind it, since feedstock costs, energy and freight all feed into intermediate pricing. Broad increases of this kind can tighten availability for customers without long-term contracts, and they can also prompt rival suppliers to review their own pricing. Buyers often respond by checking contract terms and timing of implementation.
