II. Latest Industry News (2026)

1. Accelerated domestic substitution

   Domestic styrene-acrylic surface sizing agents feature mature technology and high cost performance, gradually replacing imported products and dominating the market. Leading manufacturers have concentrated production capacity, while small enterprises face fierce homogeneous price competition.
2. Raw material price hike lifts product quotations

   Upstream raw materials including styrene and butyl acrylate keep fluctuating upward. Shutdowns of chemical plants push up production costs. Quotations of styrene-acrylic sizing agents rise accordingly and are mostly negotiated order by order.
3. High-speed compatible & eco-friendly modified products become mainstream

   New low-foam and high-stability formulas adapt to high-speed paper machines and solve film breaking and foaming problems. Bio-based, low-VOC modified styrene-acrylic products are hotspots for R&D and promotion to meet environmental policies.
4. Wide adoption of compound sizing process

   Many paper mills adopt the compound formula of styrene-acrylic agent plus a small amount of AKD to balance surface strength, water resistance and production costs, replacing traditional single sizing processes.
5. Steady growth in downstream demand

   Deteriorated quality of waste paper raw materials, rising demand for high-strength premium packaging paper and stricter environmental regulations drive market consumption. With low pollution and strong reinforcing performance, styrene-acrylic surface sizing agent sees continuous demand growth.
