1. Definition of fluorine oil
The light and middle fractions of CFCs are colorless liquids, and the heavy fractions are white greasy substances. Its density is close to 2g/ml, slightly lower than that of perfluorocarbon oil, with a slightly higher freezing point and better viscosity-wetting properties than perfluorocarbon oil. Polyperfluoroisopropyl ether is also a colorless liquid with a density of 1.8-1.9g/ml. It has a lower freezing point and good viscosity-temperature properties. Polyperfluoromethyl ethyl ether has an even lower freezing point and the best viscosity-temperature properties.
2. Application areas
Chemical industry
It can be used for highly corrosive valves, fans, pumps, agitators, reactors, centrifuges and other equipment lubricating oils, sealing oils, cooling oils, heat transfer oils, and isolation fluids.
Electronics/semiconductor industry
Low vapor pressure and high temperature anti-corrosion grease for clean rooms; Semiconductor manufacturing, vacuum system sealing oil, rotary vane pump, turbomolecular pump, diffusion pump, Roots pump vacuum pump oil, clean room, robot arm, vacuum equipment lubricating oil, bearings, valves, seals, O-rings, chains, compressors, gearboxes, mechanical pumps and other parts lubricating oil; Electronic components sealing leak detection, reliability testing, hot and cold shock experiments.
Oxygen industry
Can be used for submarines, oxygen pumps, oxygen compressors, oxygen valves or other equipment lubricating oilsealing oilcooling oilheat transfer oilisolating fluid.

3. Definition of silicone oil:
Silicone oil usually refers to linear polysiloxane products that remain in liquid state at room temperature. It is generally divided into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, has all methyl organic groups. Methyl silicone oil has good chemical stability, insulation and good hydrophobicity. It is prepared by hydrolysis of dimethyldichlorosilane with water to obtain the primary polycondensation ring body, and the ring body is cracked and distilled to obtain the low ring body, and then the ring body, capping agent and catalyst are put together to obtain a mixture of various polymerization degrees, and the low boiling point is removed by vacuum distillation to obtain silicone oil.
4. Application field
The application range of silicone oil is very wide. It is not only used as a special material in aviation, cutting-edge technology, and military technology departments, but also used in various sectors of the national economy. Its application range has been expanded to: construction, electronics and electrical, textiles, automobiles, machinery, leather and papermaking, chemical and light industry, metals and paints, medicine and medical treatment, etc.
The main applications of silicone oil and its derivatives are demolding agents, shock absorbing oils, dielectric oils, hydraulic oils, heat transfer oils, diffusion pump oils, defoamers, lubricants, hydrophobic agents, paint additives, polishing agents, cosmetics and daily necessities additives, surfactants, particle and fiber treatment agents, silicone greases, and flocculants.
