Restraint/Challenge

“Volatile Raw Material Prices”

• A key challenge for the SAN resins market is the volatility in raw material prices, particularly styrene and acrylonitrile, which are derived from petroleum. As oil price fluctuations impact input costs, manufacturers often struggle with pricing instability and uncertain margins
• For instance, producers across Asia and Europe have faced cost pressures when raw material supplies were disrupted due to global crude oil volatility, affecting resin pricing and profitability. Major suppliers such as INEOS Styrolution and Trinseo have had to balance rising costs with competitive pricing strategies to maintain market share
• The dependency on petrochemical feedstocks creates exposure to geopolitical risks, regulatory pressures on emissions, and supply chain bottlenecks. These dynamics exacerbate unpredictability in raw material procurement and challenge long-term cost planning for producers
• High volatility also impacts downstream industries such as consumer goods and automotive, as price-sensitive manufacturers must either absorb cost increases or pass them on to consumers. This can affect adoption rates and hinder the competitiveness of SAN resins against alternative polymers
• Addressing this challenge requires investment in cost-efficient production, diversification of supply sources, and integration of recycling-based feedstocks to mitigate volatility risks. Enhancing supply chain resilience will be essential for stabilizing costs and ensuring the continued growth of the SAN resins market
