There are three main types of fluorine we know, C8, C6, and C4. Because the production process of C8 includes telomerization method and electrolysis method. In the process of synthesizing C8 by telomerization method, PFOA or PFOS are not used as raw materials for production. These two substances are not added during the production process. However, a small amount of PFOA impurities will be produced during the production process of the telomerization process; C8 in the electrolytic synthesis process is used, and PFOS is inevitably formed during the synthesis of polymer monomers. PFOS is one of the organic pollutants known to be difficult to degrade. It has high bioaccumulation and multiple toxicity. It not only causes human respiratory system problems, but may also lead to the death of newborn babies. The global pollution caused by it is increasingly affected. People pay attention. Although C4 contains PFBS (perfluorobutanesulfonate) and C6 contains PFHxA (perfluorohexanoic acid), their decomposition cycle is significantly shorter (5.3 hours), and the environmental pollution is much smaller. . Moreover, PFOA will not be produced during the synthesis process, so C6 can pass. The EU decree issued in 2006 stipulates that the PFOS content in textiles exported to the EU must be less than 1 μg/m2, while C8 is difficult to pass.
