According to the structure of the carbon chain, it can be divided into C8, C6, and C4 are collectively called fluorine series.
C8 has excellent effects and is affordable. It has been used by major textile and leather industries many years ago. However, C8 contains PFOA (perfluorooctanoic acid and salts), PFOS (perfluorooctane sulfonyl compound) and APEO (alkylphenol polyoxyethylene). ether). PFOA, PFOS and APEO are currently difficult to degrade in the environment. They are bioaccumulative and have multiple toxicities. They have the common characteristics of persistent organic pollutants. They are considered to be new persistent environmental pollutants that are focused on research in the 21st century. Their sources It is mainly a fluorine-based waterproof and oil-repellent agent.
The main component of C6 is PFHS (perfluorohexane sulfonyl compound or sulfonate), which is an ideal product to replace C8 containing PFOA and PFOS. For the textile industry, the main source of PFOA and PFOS is fluorine-based waterproofing Oil repellent. Therefore, the EU decree issued in 2006 stipulated that the content of PFOS and PFOA in textiles exported to the EU must be less than 1ug/㎡; at that time, it was difficult for C8 on the market to meet the requirements, and the PFOS and PFOA content in C6 was less than the regulations. Numerical values are generally difficult to detect, so it has been widely used instead of C8. However, in terms of effect and price, C6 is expensive, but its effect is difficult to match C8.
As global environmental protection pays more and more attention, the U.S. Environmental Protection Agency has clearly stipulated that by 2015, the use of C8 and C6 containing PFOA and PFOS will be banned globally, and C4 and fluorine-free are strongly recommended. In 2015, fluorine-free became popular in the textile industry use.
What is fluorine-free?
Fluorine-free, completely free of APEO, no Contains PFOA and does not contain PFOS. It is a good alternative to organic fluorine.
Fluorine-free development trend:
In 2015, the use of C8 and C6 was banned globally, and fluorine-free products replaced them, becoming a product that attracted much attention in the global textile industry. It does not contain any PFOA, PFOS and APEO, has excellent waterproof effect and is washable.
