As one of the three fluorinated monomers, Hexafluoropropylene can be used to prepare a variety of fluorinated fine chemical products, pharmaceutical intermediates, fire extinguishing agents, etc. . The invention can also be used as raw materials for preparing fluorosulfonic acid ion exchange membrane, fluorocarbon oil, perfluoroepoxypropane and the like. It is one of the main products of fluoropolymer division of Juhua Co. , Ltd. .
The Hexafluoropropylene is polymerized with the tetrafluoroethene monomer to form FEP.
Fluorinated ethylene propylene (FEP) is a kind of soft plastic. Its tensile strength, wear resistance and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant (2.1) over a wide temperature range. The material does not ignite and can prevent the spread of the flame. It has excellent weather resistance, low friction coefficient and can be used continuously in the temperature range of-85-200 °c. even under the limit of-200 °C and + 260 °C, its performance does not deteriorate and can be used for a short time.
The material can be made into granular products for extrusion and molding, powders for fluidized beds and electrostatic finishing, and aqueous dispersions. Semi-finished products are membrane, plate, Rod and single fiber. Its main use is in the lining of pipes and chemical equipment, the surface of rollers and various wires and cables, such as airplane Hook Lines, pressurization cables, alarm cables, flat cables and oil well logging cables. FEP films have been used as thin coatings for solar collectors.
Hexafluoropropylene is polymerized with vinylidene fluoride monomer to produce 26 fluororubber, commonly known as glue No. 2 in China.
26 fluororubber is formed by reaction of vinylidene fluoride (VDF) and Hexafluoropropylene in a certain proportion. Its stability, high temperature resistance, aging resistance and electrical properties (volume inherent resistance) are excellent. Mainly used in modern aviation, missiles, rockets and other cutting-edge technology and automotive, shipbuilding, chemical and other industrial fields.
Hexafluoropropylene is polymerized with vinylidene fluoride and tetrafluoroethene monomer to produce 246 fluororubber, commonly known as No. 3 in China.
246 fluororubber is prepared by the reaction of vinylidene fluoride (VDF) , tetrafluoroethene and hexafluoropropylene (HFP) in a certain proportion. The properties of stability, high temperature resistance, aging resistance and electrical properties (volume inherent resistance) are excellent. Mainly used in modern aviation, missiles, rockets and other cutting-edge technology and automotive, shipbuilding, chemical and other industrial fields. Compared with 26 fluororubber, 246 fluororubber has higher fluorine content and better solvent resistance.
The Hexafluoropropylene reacts with Hf gas to prepare the 1,1,1,2,3,3,3-Heptafluoropropane.
The 1,1,1,2,3,3,3-Heptafluoropropane has been widely used in various fields. The 1,1,1,2,3,3,3-Heptafluoropropane is environmentally friendly, has a short retention period in nature, has high fire fighting efficiency, and is non-toxic and harmless at a certain design concentration, for protected areas with permanent staff. The 1,1,1,2,3,3,3-Heptafluoropropane fire fighting system is designed to be totally submerged, and chemical fire fighting is the main way to put out fires. In the design concentration of the state of no fire inside the body without damage!
Preparation of Hfo-1234yf by reaction of Hexafluoropropylene with hydrogen.
HFO-1234yf, a new generation automotive air conditioning refrigerant, is typically characterized by a low global warming potential and is a potential and economical direct alternative to automotive air conditioning systems using R134A. The results of bench test and vehicle performance test show that the refrigeration capacity and the deviation of ∞ p from the original R134A system are about 5.
As for the compatibility of materials, Poe and PAG lubricants can be used directly. No adverse reaction was found in the compatibility with rubber and the sealing of hose. The results of the risk test showed that the refrigerant was of low toxicity and lower toxicity than R134a, and the in-vehicle leakage test showed that the refrigerant leakage would not lead to combustion aggravation in the presence of open flame.
Preparation of hexafluoropropylene oxide (HFPO) by reaction of Hexafluoropropylene with oxygen. Hexafluoropropylene oxide is an important intermediate for the synthesis of fluorine-containing fine chemicals, which can be used in the production of PPVE, perfluoroacetone, Fluorosurfactant, etc. .
