Founded in 1958, the predecessor of Xinjiang Zhongtai Group built Xinjiang’s first chlor-alkali production enterprise. Caustic soda served as the core launch product of the group, and it remains the pillar business with the earliest launch, first commissioning and most complete industrial chain supporting facilities across the group’s development journey spanning over six decades.
After more than 60 years of technological iteration and capacity expansion, leveraging Xinjiang’s abundant natural resources including coal, crude salt and limestone, the group has established an integrated circular economy industrial chain: Coal – Thermal Power – Calcium Carbide – Chlor-Alkali – Viscose Fiber. At present, its ionic membrane caustic soda production capacity ranks first nationwide in China’s industry.
The group’s total designed capacity of ionic membrane caustic soda hits 1.86 million metric tons per year, with capacity rationally distributed across four major production bases: Fukang Energy (660,000 tons/year), Huatai Heavy Chemical Industry (580,000 tons/year), Shengxiong Energy (400,000 tons/year) and Toksun Energy & Chemical (220,000 tons/year). The total capacity of solid caustic soda reaches 1.4 million metric tons annually.
The group’s core flagship product is high-purity ionic membrane solid caustic soda, divided into three well-positioned categories: 98% flake sodium hydroxide for industrial general use, food-grade solid sodium hydroxide additive, and 99% granular sodium hydroxide. All products are manufactured under full-chain self-supplied green power management, with core product indicators and impurity control outperforming national superior-grade standards. Each product category targets distinct application scenarios with clear market positioning.
This white flake industrial caustic soda maintains stable purity above 98% with highly consistent physical and chemical indicators across all production batches, making it the mainstream staple product for the domestic market. It primarily caters to the massive demand of alumina smelting, and is also widely applicable to general industrial sectors including pulp and papermaking, textile printing and dyeing, wastewater treatment, and chemical synthesis.
This low-impurity, high-purity flake caustic soda strictly complies with the national standard GB 1886.20-2016 for food additives. All heavy metal contents are controlled below national standard limits, and the entire production process follows GMP specifications. It meets high-standard compliance requirements of the food and pharmaceutical industries, suitable for food equipment cleaning and disinfection, edible oil refining, pharmaceutical purification, drinking water treatment and other related applications.
Featuring uniform and neat granules, this product delivers excellent fluidity, zero dust generation and fast dissolution speed, with far superior metering accuracy compared to flake caustic soda. Designed for high-cleanliness and high-precision production processes, it is widely adopted in precise batching for lithium new energy, continuous production of fine chemicals, premium daily chemicals, petroleum refining and other sectors.
The group’s full lineup of solid caustic soda products covers core domestic industrial segments including alumina, papermaking & textiles, water treatment and fine chemicals. With stable supply and consistent reliable quality, we have long-term supported industrial clients across diverse domestic sectors with comprehensive matching solutions.
Drawing on over six decades of accumulated chlor-alkali expertise, complete integrated industrial chain layout and low-carbon production powered by self-generated green electricity, Xinjiang Zhongtai Group will continuously amplify its core competitive advantages. Adhering to the market-oriented and customer-first business philosophy, supported by a sound, efficient logistics network and one-stop supporting services, we stand ready to cooperate with all partners to explore market opportunities and achieve win-win sustainable development together.
Committed to quality, innovation, and reliable chemical solutions for a sustainable future.
