China Antiscalants Market Size, Share & Trend Analysis Report By Product Type (Carboxylates, Phosphonates, Sulfonates, Fluorides), By Application (Coal Gasification, Chemical, Power), And Segment Forecasts, 2025 - 2030

China Antiscalants Market Growth & Trends

The China antiscalants market size is expected to reach USD 854.1 million by 2030, according to a new report by Grand View Research, Inc. The market is estimated to expand at a CAGR of 6.8% from 2025 to 2030. Rise in the offshore oil and gas facilities accompanied by increased coal-fired power generation in China is augmenting the demand of antiscalants. Antiscalants are preferred over acids as they inhibit the formation of nearly all types of scales such as colloids, and metal oxides formed from fluorides, sulfates, calcium carbonate, and calcium phosphate.

They also control scale formation at a better rate than sulfuric acids, when used in smaller doses. Antiscalants can be used in various industries such as coal gasification, power, and chemical. In the oil and gas industry, antiscalants are used to prevent scale formation during exploration, treatment, and transportation phases. Among the chemicals, phosphonates are widely used in the corrosion and scale iron sequestrates and inhibitors in water treatment process. They act as a super threshold agent in the membrane system.

n the other hand, the impact of using such chemicals may lead to the loss of aquatic organisms by entrainment and impingement. However, continuous government support for the development of eco-friendly products will fuel the demand from 2025 to 2030. The chemical industry led the market with the largest revenue share in 2024. Antiscalants are used to mitigate the formation of recycled water in thermal power plants. In addition, growing usage of antiscalants in power sector applications and coal gasification sector would also propel industry expansion.

China Antiscalants Market Report Highlights

• The phosphonates segment dominated the market and accounted for the largest revenue share in 2024 and the the carboxylates segment is expected to grow at a CAGR over the forecast period
• The chemical industry led the market with the largest revenue share in 2024 and the power industry is expected to grow at the fastest CAGR from 2025 to 2030
• In terms of volume, carboxylates were the second-largest segment in 2024. Positive power sector outlook in China due to abundance of mineral reserves coupled with regulatory support encouraging foreign investments would boost the applications of carboxylates and phosphonates, thereby augmenting the market growth
• Presence of a large number of suppliers and continuous R&D activities undertaken by various manufacturers to improve the production volumes is also expected to drive the market in the years to come.
