How the refrigerant industry responds to PFAS is quickly emerging as one of the defining environmental questions of our time. Yet despite rising global attention, there is still no universally harmonized definition of PFAS, and the scope of substances under discussion continues to evolve.
In this context, meaningful progress depends on moving beyond broad classifications toward clearly defined, technically actionable pathways.
One key area of focus is trifluoroacetic acid (TFA), widely recognized as a common terminal degradation product of certain fluorinated chemical systems. Its persistence and mobility in aquatic environments have made TFA a long-term subject of both scientific investigation and regulatory consideration.
At Quanzhou Yuji Advanced Materials Co., Ltd., this challenge is addressed at the level of molecular design.
Our founder brings more than three decades of experience in CFC alternative research, with a sustained focus on global environmental trends and the evolution of regulatory frameworks. In 2024, we introduced in China the concept of “Fifth-Generation CFC Alternatives,” developed to respond to emerging environmental expectations across refrigerants, blowing agents, and related applications.
In 2025, this technical framework was presented internationally for the first time at the National PFAS Symposium in Australia by Yuji experts.
Today, Yuji’s fifth-generation refrigerant products have entered downstream application testing in China, as well as in selected markets in Europe and North America, meeting both performance objectives and environmental design criteria.
As evaluation frameworks expand beyond ODP and GWP to include environmental fate and degradation pathways, refrigerant innovation is entering a new stage.
The PFAS discussion is therefore not only about restriction — it is increasingly about long-term chemical redesign and forward-looking molecular engineering.
