With the tightening of global environmental regulations and the acceleration of green transformation in manufacturing, the environmental performance of metalworking fluids (cutting fluids, grinding fluids, etc.) has become a focus of industry attention. As a key additive in machining fluids, the environmentally friendly and efficient development of defoamers is also facing new opportunities and challenges.   

The components such as organosilicon and mineral oil in traditional defoamers are limited in some markets due to their poor biodegradability or the presence of volatile organic compounds. For example, the European Union has implemented usage restrictions on some polysiloxane defoamers, and China's "dual carbon" goals are also driving the transformation of the processing fluid industry chain towards low toxicity and degradability.   

At present, nanotechnology and intelligent responsive defoamers are receiving increasing attention from the industry. Nanoparticles enhance the stability of defoamers, while intelligent responsive defoamers can trigger defoaming actions based on the pH or temperature of the processing fluid, improving resource utilization. But at present, there are also many difficulties and challenges encountered, such as high production costs and difficulties in large-scale production.   

Currently, environmental trends are reshaping the defoamer industry for metalworking fluids. In the future, products that combine high performance and sustainability will dominate the market, and interdisciplinary cooperation and collaborative carbon reduction across the entire industry chain will be key breakthroughs.
