R245fa domestic production capacity will expand rapidly

As the R245fa foaming technology is relatively mature, it is expected that domestic fluorine chemical companies will start the construction of the R245fa project in 2016, and the industry's production capacity will increase from the existing 12,000 tons as a new starting point to achieve localization, thereby driving demand growth.

After my country completely phased out the first-generation blowing agent (fluorocarbon) R11 in 2010, the second-generation blowing agent R141b and cyclopentane during 2011-2015 It has become a substitute for R11 and is widely used in refrigerators, freezers and water heaters. With the improvement of national environmental protection requirements and energy efficiency standards, R245fa and R365mfc, as transitional substitutes, have become the third-generation blowing agents that replace cyclopentane and R141b. Among them, the United States and Japan tend to use R245fa, while the European Union is more willing to use R365mfc.

At present, China is accelerating the phase-out of (hydrochlorofluorocarbon) HCFCs. As a transitional product, R245fa belongs to (hydrofluorocarbon) HFCs. The country has no policy restrictions on HFCs for the time being. , But because of the high GWP value, the country discourages promotion. At the same time, international giants Honeywell and DuPont advocated (hydrofluorooxyolefin) HFO olefins R1233zd trifluoropropylene (LBA), R1336mmz (hexafluorobutene) FEA-1100 instead of R245fa and R365mfc to become the fourth generation of foaming Agent.

In addition, Honeywell's R245fa preparation patent expired on July 5, 2015. The lifting of the patent ban may break the disadvantages of the original foreign monopoly. Localization will make The price is more close to the people, which is conducive to market promotion. According to industry insiders, only minor changes are needed to replace the blowing agent equipment. The current promotion is not good, mainly because R245fa is more expensive than R141b.

In view of the relatively mature R245fa foaming technology, it is expected that in 2016, domestic fluorine chemical companies will set off an upsurge in the construction of R245fa projects, and the industry's production capacity will increase from the existing 12,000 tons as a new starting point. , Realize localization, and then promote demand growth.
