Fujian Zhanhua Chemical Co., Ltd. ranks among the world’s‑largest‑scale persulfate manufacturers (according to public information released by the Department of Industry and Information Technology of Fujian Province, Zhanhua Chemical holds world‑leading production capacity for ammonium persulfate, sodium persulfate and potassium persulfate). With more than 20‑year dedication to the persulfate sector, its core portfolio covers three major categories: ammonium persulfate, sodium persulfate and potassium persulfate. Complementary in production scale, application scenarios and quality positioning, the three product lines satisfy full‑scenario demands ranging from bulk industrial uses to high‑end fine‑chemical applications. The company’s Phase‑III technical renovation and expansion project is currently under advancement, focusing on the development of electronic‑grade and temperature‑resistant persulfate products. Main‑structure construction of two production plants has been completed. Full civil‑engineering works are expected to finish in November 2026, equipment installation will be carried out in 2027, and commissioning for operation is scheduled for March 2028. Upon completion, production capacity for all three core products will be further expanded.
Ⅰ Ammonium Persulfate: World‑Leading Production Capacity Built upon Single‑product Growth
Ammonium persulfate represents the highest‑volume core product of Fujian Zhanhua Chemical, with an existing annual output of 75 000 tons. After the Phase‑III project goes online, its capacity will rise to 135 000 tons. Such large‑scale capacity stems from 20 years of continuous expansion: the comprehensive capacity reached 10 000‑ton level in 2008, hit 30 000 tons in 2013, exceeded 50 000 tons in 2018, and was further lifted to the current 75 000‑tons‑per‑annum through successive technical upgrades.
In chemical manufacturing, ammonium persulfate is widely adopted as an initiator for polymerization reactions, playing a vital role in synthesizing acrylic resins, synthetic rubber and other polymer materials. It is also extensively used in metal processing for chemical etching and surface finishing of aluminium and copper materials. Leveraging its large‑scale production capacity, the company delivers stable supply guarantees and flexible delivery schedules for customers, effectively mitigating risks associated with supply‑chain volatility.
Ⅱ Sodium Persulfate: Standard‑setting Strength behind the Single‑Champion Product
Sodium persulfate is the company’s flagship product. The “Zhanhua‑brand sodium persulfate” has been awarded the National Manufacturing Single‑Champion Product title by the Ministry of Industry and Information Technology, recognizing its leading position and quality competitiveness within the market segment. Its current annual production capacity stands at 50 000 tons, which will increase to 90 000 tons after Phase‑III project commissioning, bringing substantial improvement to market supply capability.
Sodium persulfate serves diverse industries. In the electronics sector, it acts as a key oxidant for copper‑surface micro‑etching of printed circuit boards (PCB), directly influencing circuit‑board manufacturing quality. In environmental protection, under specific activation conditions, it generates highly‑oxidative sulfate‑radical species to efficiently degrade organic contaminants in soil, functioning as a core reagent for site‑contamination remediation.
Furthermore, the company is deeply engaged in industry‑standard development. It has led and participated in formulating four national standards, two industry standards and two association standards, and took the lead in drafting the industry standard Sodium Persulfate for Soil Remediation. This establishes a full‑dimensional layout covering product manufacturing, quality control and industry‑rule formulation. These standards provide downstream users with clear quality references and product‑selection basis, further consolidating its market influence within the niche segment.
Ⅲ Potassium Persulfate: Reliable Supply for High‑end Niche Markets
The company’s existing annual capacity of potassium persulfate reaches 12 000 tons and will be upgraded to 22 000 tons after Phase‑III project completion, sufficiently supporting stable procurement for high‑end niche applications. Compared with the other two persulfate varieties, potassium persulfate targets more focused use cases: it is mainly applied as an initiator in polymer‑polymerization processes, requiring superior purity and dissolution performance for quality‑sensitive sectors such as coatings, adhesives and fine chemicals.
For purchasers, consistent batch‑to‑batch performance directly determines polymer product quality stability, making suppliers with mature quality‑management systems particularly critical. To match high‑end‑market requirements, Zhanhua has implemented stringent quality‑control workflows and obtained certifications including ISO 9001 Quality Management System, ISO 14001 Environmental Management System, ISO 45001 Occupational Health and Safety Management System and ISO 50001 Energy Management System. Full‑process production supervision ensures batch consistency and underpins stable quality for downstream high‑end finished goods.
Ⅳ Intelligent Green Manufacturing and Full‑chain Support: Consolidating Core Competitiveness in Global Markets
For sustainable‑development practice, Zhanhua has built a closed‑loop three‑waste recycling production system and been accredited as a National‑level Green Factory. It also holds the national‑level Specialized, Refined, Differential & Innovative “Little Giant” Enterprise and National High‑tech Enterprise qualifications. Sustained R&D investment and rigorous quality control enable the company to consistently deliver national‑standard superior‑grade products, alongside custom‑tailored solutions upon client request.
In global‑service operations, benefiting from the scale capacity and quality advantages of its three persulfate lines, Fujian Zhanhua Chemical’s products are widely deployed across electronics, petroleum, environmental protection, daily‑use chemicals, pesticide intermediates and other industries. Domestically, it maintains mature hazardous‑goods warehousing and distribution networks. Internationally, its business covers more than 40 countries plus Hong Kong, Macao and Taiwan regions of China, supported by a well‑established global service system.
With over two decades of dedicated operation, Fujian Zhanhua Chemical has built complete industrial advantages spanning manufacturing to global service via differentiated portfolio layout of its three persulfate products, continuous capacity expansion and strict quality governance. As the Phase‑III technical‑renovation‑and‑expansion plan comes into fruition, the company will further boost output capacity for high‑end grades such as electronic‑grade and temperature‑resistant persulfate, keep expanding its global footprint, and empower the high‑quality and green‑oriented development of the persulfate industry.
