Current situation and Application Field of Fluorine Containing Polymer Industry
- May 30, 2018 -

          In recent years, the fluorine chemical products have been widely used in various fields, especially the emerging industries. However, the ability of independent innovation in industry is weak, the structure of industry and product is out of balance, and the development mode of winning by quantity has come to an end. In the current fluorine chemical industry, the low end products are overcapacity and disorderly, and the innovation ability of high-end products is insufficient. Contradictions, fluorine chemical industry is focusing on industrial innovation driven development issues, and strive to make breakthroughs in fluorine containing fine chemicals, equipment technology development and other fields.

According to the national "12th Five-Year" new material industry development requirements, in the fluorine chemical industry, we should establish a fluorine material industry system with large scale, strong independent innovation ability and a complete set of industry, and cultivate a batch of core enterprises with core competitiveness to form a batch of industrial bases with reasonable layout, bright features and industrial agglomeration. A small gap.

Application field of common fluoropolymer:


Polytetrafluoroethylene can be made by compression or extrusion processing; it can also be made into water dispersion, used in coating, impregnation, or fiber. Polytetrafluoroethylene is widely used in such industries as atomic energy, defense, space, electronics, machinery, instrumentation, construction, textile, metal surface, pharmaceutical, medical, textile, food,and metallurgy. High and low temperature, corrosion resistant materials, insulating materials and anti sticking coatings make it an indispensable product.


Six fluorine propylene (HFP) is a widely used fluorine containing intermediate. It has high chemical activity and can carry out various types of chemical reactions. It is a raw material for preparing a variety of fluorine containing fine chemicals, pharmaceutical intermediates, fire extinguishing agent HFC-227ea, and so on. Together with other alkenes, FKM-26, FKM-246 and other fluoropolymers can be obtained.


Polyvinylidene fluoride (PVDF) resin is an homopolymer of vinylidene fluoride (VDF). It can be used as fluorocarbon coating, lithium battery adhesive, fluorine film, new fluorine containing material, etc.

Foreign PVDF is mainly used in the field of architectural coatings (about 40.8%), chemical processing (about 34.2%) and wire / cable area (about 17.1%), and other fields 7.9%.

The main amount of PVDF used in China is emulsion products, which is used in fluorocarbon coatings industry, accounting for 85% of the market consumption, and the resin is only 15% of the market. It is mainly used in wire and cable. "Petroleum and chemical industry" in 12th Five-Year "program for development of science and technology" pointed out that the proportion of non polytetrafluoroethylene (including PVDF) in fluorine resin in China is only 11%, far below the developed. About 40% of the country undefineds proportion, China undefineds future fluoropolymer will focus on the development of PVDF and other non PTFE varieties, and gradually improve the proportion of non PTFE resin.

Polyfluoroethylene propylene (FEP) resin has similar characteristics to polytetrafluoroethylene and good processing technology for thermoplastic plastics, thus making it an important material to replace polytetrafluoroethylene, which is widely used in electric wire and cable production, the transmission line of electronic equipment used at high temperature and high frequency, the connecting line inside the electronic computer, the aerospace universe. Wires, and other special purpose installation lines, oil and mineral logging cables, submersible motor winding wires, micro motor lead lines, etc.

Fluorine rubber,that is FKM, Viton

Fluorine rubber is mainly used in automobile, defense, military, aerospace, electronic communications, vehicle and ship, petrochemical, machinery and other fields.

Fluoroelastomer (FKM-26) is a copolymerized fluorine elastomer of vinylidene fluoride and six fluorine propylene. The product has a flaky appearance. The fluorine content is 65%. from the fluoroelastomer (FKM-26). The product has excellent oil resistance (various fuel, synthetic oil, lubricating oil) and high temperature heat resistance. It can be molded or extruded to produce various O rings, seals, and septum. Membranes, gaskets, films, valves, hoses, cots and other rubber products.

Fluoroelastomer (FKM-246) is a fluorine-containing elastomer with three fluorinated ethylene, tetrafluoroethylene and six fluoropropene. The product has a white appearance and a fluorine content of 67%..

The products made of FKM-246 and vulcanization have excellent oil resistance (all kinds of fuel, synthetic oil, lubricating oil) and high temperature heat resistance. It can be molded or extruded to make all kinds of 0 rings, seals, diaphragm, gaskets, film, valve, hose, rubber roll and other rubber products.
