 — Deeply rooted in the fine chemical industry, our three core products help customers reduce costs and improve efficiency.

Recently, the U.S. publication Chemical & Engineering News (C&EN) released its ranking of “The World’s 50 Largest Chemical Companies in 2026.” According to the data, driven by overcapacity in the petrochemical industry, the chemical sector is experiencing its most severe downturn yet. In fiscal year 2025, the total revenue from chemical sales for the 50 largest chemical companies reached $965.8 billion, a 5.8% decrease compared to fiscal year 2024. Among these companies, 39 saw a decline in sales. Of the 37 chemical companies covered in the report, operating profits fell by 19.5% year-on-year to just $47.2 billion; 25 companies reported lower profits, and 7 suffered losses. Against the backdrop of overall industry pressure, Shijiazhuang Pengnuo Technology Co., Ltd. (hereinafter referred to as “Pengnuo Technology”) has demonstrated strong resilience and robust growth momentum by leveraging its solid technological foundation and stable product quality. With years of deep expertise in the fine chemical industry, the company focuses on three core ester products—ethylene glycol diacetate, diethylene glycol diacetate, and ethylene glycol diacetate—and continuously provides high-quality chemical solutions for downstream sectors such as textiles, coatings, pharmaceutical intermediates, and daily chemical products. During the industry’s downturn, the company has earned widespread customer trust.

“Those Who Go Against the Grain” in the Industry’s Winter: Breaking the Impasse with Product Strength

The report by C&EN reveals a clear signal: the chemical industry is undergoing a period of profound adjustment, with intensifying price competition driven by overcapacity. However, crises also bring opportunities—downstream customers are not only maintaining but actually increasing their demand for intermediates and specialty solvents that offer high cost performance and stable quality. This creates room for fine-chemical companies with core technological advantages and large-scale production capabilities to differentiate themselves in the market.

Pengnuo Technology has always adhered to a market-oriented approach and driven by technological innovation, continuously optimizing its product portfolio and enhancing its quality control standards. The company’s three major ester products have earned an excellent reputation in both domestic and international markets thanks to their high purity, excellent stability, and outstanding cost-effectiveness.
