I. Current Development Status: Technological Iteration and Market Reshaping
Block silicone fluids, as specialty silicone polymers, achieve targeted adsorption on fiber surfaces through a siloxane-polyamine-polyether ternary copolymer structure. The domestic market size exceeded 420,000 tons in 2025, with an annualized growth rate of 8.5%. Their application areas have expanded from traditional textiles to include daily chemicals, electronics, rubber, and other fields. Textile finishing accounts for 58%, daily chemicals and personal care products account for 28%, and high-end applications such as electronic mold release account for 14%. On a technical level, the industry exhibits three major trends:
Green Transformation: The market share of bio-based block silicone fluids (such as Siligen® EH1, which contains 35% plant-based ingredients) has increased to 12%, complying with EU REACH and ZDHC zero-emission standards;
Functional Upgrade: Polyether-modified products, due to their water solubility, account for 62% of the market share, while amino block silicone fluids, with their antistatic properties, have a strong presence in the high-end market;
Process Optimization: Self-emulsifying systems have surpassed compatibility under extreme pH conditions of 3-12, achieving a 98% yield rate when used in the same bath with anionic dyes.
In the competitive landscape, Zhejiang Huangma Technology leads with an annual production capacity of 85,000 tons, followed closely by Jiangsu Demei Technology and Guangzhou Tianci Materials. Together, these three companies account for 47% of national production capacity. Foreign brand Momentive, leveraging its technological advantages, holds a 15% share of the high-end market.

II. Outlook: Demand-Driven and Industrial Ecosystem Restructuring
Over the next five years, the segmented silicone fluid market will experience three growth drivers:
Textile industry upgrade: With surging demand for functional fabrics, the application of segmented silicone fluids in sportswear and outdoor equipment is expected to increase by 12% annually;
Expansion in the daily chemical sector: The reliance on functional silicone fluids in mid- to high-end cleaning and care product formulations has increased to 35%, driving the personal care market to exceed 2 billion yuan;
Rise of emerging markets: The relocation of textile production capacity in Southeast Asia and the Middle East is driving export demand, with exports expected to increase by 18% year-on-year in 2025.
Technological breakthroughs will focus on the development of nano-dispersions and low-VOC (volatile organic compound) products. By 2030, green products are expected to account for over 40% of the market. Amidst accelerating industry consolidation, companies with a full industry chain presence (e.g., from silicon block production to end-use additives) will dominate the market, while small and medium-sized enterprises will need to find niche markets through differentiated products (such as specialty release agents).
