1. Refrigerant: Fluorochemical products such as Freon are a kind of common refrigerants, which are widely used in refrigerators, air-conditioners, cold storage and other refrigeration equipment.
2. Blowing agent: Some fluorochemical products such as perfluorooctanoic acid (PFOA) have been used as blowing agents in the production of polyurethane foam, carpets, furniture and other products. However, due to the potential hazards of PFOA to human health and the environment, it has been gradually replaced by other alternatives.
3. Chemical intermediates: Fluorochemicals are important intermediates in many organic chemical reactions, and are used in the production of various chemicals, such as drugs, pesticides, surfactants and so on.
4. Polymer materials: fluorine polymers have excellent heat resistance, chemical resistance and weather resistance, and are widely used in a variety of engineering plastics, rubber, coatings, fibers and other fields. For example, polytetrafluoroethylene (PTFE, commonly known as Teflon) is a widely used coating material for non-stick pans.
5. Electronic materials: fluorine chemical products have a wide range of applications in the electronics industry, such as perfluorocarbon electrolytes, used in the production of lithium batteries, solar cells and so on. In addition, fluoride is also used as etching gas and cleaning agent in the semiconductor manufacturing process.
6. Fire extinguishing agent: Fluorochemical products such as hexafluoropropane (HFC-236fa) is a highly efficient and environmentally friendly fire extinguishing agent, which is widely used in fire fighting systems.
7. Medical field: Fluorine chemical products are also used in the medical field, such as fluoride mouthwash can effectively prevent dental caries, and perfluoropropane gas (PFP) can be used as a conductor of medical ultrasound.
In short, fluorine chemical products have a wide range of applications in modern industry and commerce, involving refrigeration, foaming, chemical synthesis, materials, electronics, fire protection, medical and other fields.
