Since 2026, fluctuations in crude oil prices have driven a sharp increase in the prices of chemical raw materials. The price of acrylic emulsion for coatings has risen by about 47%, asphalt for waterproofing has increased by 53%, and epoxy resin has risen by 30%, which has directly pushed up the production costs of building materials enterprises. Faced with cost pressure, different types of building materials enterprises have adopted differentiated response strategies: small and medium-sized bathroom enterprises have launched stainless steel products to replace copper materials; new material enterprises have relied on solid waste raw materials to reduce the impact of costs; leading decorative material enterprises have transmitted costs through technological innovation, high-end differentiation and price increases, further improving the industry concentration.
