As a comprehensive company specializing in fluoropolymer-related businesses, Alfa Chemistry Fluoropolymers is also committed to developing environmentally friendly fluoropolymer recycling business. We are willing to purchase fluoropolymer waste from factories or help customers recycle fluoropolymer waste.
Due to its special properties, PTFE has a large melt viscosity, and it hardly flows when it reaches the melting point. It will decompose when the temperature rises. Therefore, it cannot be recovered by melt polymerization and injection molding methods like ordinary thermoplastic resins. Driven by catalytic technology, chemical recycling has shown good economic prospects. The chemical recovery of PTFE by the high-temperature cracking method can not only directly convert it into monomer, but also upgrade it and regenerate it.
Pyrolysis is to decompose PTFE into small molecules at a high temperature of 425 °C to 700 °C, and then recover useful small molecules; sometimes in order to obtain certain small molecules, the pyrolysis temperature can be as high as 800 °C.
Among the available small molecule compounds are tetrafluoroethylene (TFE), hexafluoropropylene (HFP), octafluorocyclobutane (OFCB), octafluorobutene (OFB), etc. At the same time, a small amount of octafluoroisobutene is also produced (OFB), fluorophosgene (COF) and other highly toxic substances, which should be avoided and controlled during the operation.
545°C to 600°C (1013°F to 1112°F)
Tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and cycloperfluorobutane (c-C4F8).
