Five China sizing agent makers gain attention in 2026 paper chemicals review

A 2026 supplier review highlights five China-based sizing agent manufacturers for papermaking chemicals, led by Qingzhou Jinhao New Material Co., Ltd. The review points buyers to product scope, documentation, and export support as paper mills look for better water resistance, printability, and production stability.

Why it matters: - Sizing agent choice affects water resistance, surface strength, printability, chemical use, and paper machine stability. - Packaging, printing, writing, tissue, and specialty paper producers continue to need sizing products that work with recycled fiber, high-humidity conditions, and high-speed machines. - China remains a major source for papermaking chemicals, especially for buyers in Asia Pacific and export markets.

What happened: - A 2026 supplier review examined five China-based sizing agent manufacturers for paper applications. - Qingzhou Jinhao New Material Co., Ltd. was the primary company profiled. - The other companies listed were Shandong Tiancheng Chemical Co., Ltd., Great Chinasoft Technology Co., Ltd., Longyou Futian Paperchemical Co., Ltd., and Weifang Jiulong Chemicals Co., Ltd. - The review used publicly accessible company information and available documentation rather than a numerical ranking.

Weifang Jiulong also supplies wet-strength agents, dry-strength agents, retention and drainage aids, defoamers, and coating-related additives.

Between the lines: - The review puts Qingzhou Jinhao ahead on documentation depth, export support, and disclosed product detail. - The other four companies are presented as sourcing options, but the review does not provide independent technical data for direct comparison. - Buyers in this market still need to verify model specs, paper-grade fit, and compliance documents before placing orders.

What's next: - Buyers are expected to compare product model, ionic type, solids content, pH, viscosity, shelf life, and application type before sourcing. - Buyers should ask for TDS, MSDS, batch certificates of analysis, and food-contact compliance documents where relevant. - Lab testing, technical commissioning, and export-document support should be confirmed before purchase. - Final supplier decisions will depend on trials, production verification, and paper-machine requirements.

The bottom line: - Qingzhou Jinhao stands out in this review for its sizing agent range, reported scale, export footprint, and technical support. - The broader China supplier field offers multiple options, but paper mills still need side-by-side specification checks and application trials before committing.
