Comparison between EPDM and fluorine rubber

Comparison between EPDM and fluorine rubber. In terms of resistance to chemical acid and alkali corrosion, fluorine rubber or EPDM rubber sealing rings are generally used. To put it simply, the difference between the two: fluorine rubber has wider chemical resistance and some fluorine rubber has temperature resistance. It can reach a higher temperature, while the EPDM rubber ring can only reach a certain temperature. Fluorine rubber can withstand oil accumulation media, but EPDM rubber cannot. The advantage of EPDM rubber is that it is relatively cheap and is often used in sewage treatment or other water treatment products.
Corrosion-resistant EPDM rubber sealing ring in terms of rubber materials: EPDM rubber itself has excellent performance in terms of high temperature resistance, wear resistance, corrosion resistance, etc., and it can well reflect its own tensile strength. The amount of deformation can reach more than %. But the disadvantage is that it cannot come into contact with oil such as gasoline, diesel, hydraulic oil, etc. If the medium contains oily substances, the sealing ring will expand or be eroded away. Therefore, it is widely used in drinking water treatment, sewage treatment, other sealing, and other oil-free occasions.
In terms of rubber materials for acid and alkali corrosion resistant fluororubber rings: the English name of fluororubber is the abbreviation of the fluororubber material produced by DuPont. Yidan Seal Company chooses DuPont from the United States for the fluorine rubber material. Because of the good selection of rubber materials, the quality of the company's seals has always been stable and has been recognized by customers. The comprehensive performance of fluorine rubber is very good, whether it is oil resistance, high temperature resistance, wear resistance, and corrosion resistance. The commonly used colors of fluorine rubber sealing rings are brown and black. Green can also be made into other colors.
Molecular structure and performance of fluorine rubber rings: There are various types of rubber containing fluorine in the molecule depending on the fluorine content (i.e. monomer structure). The currently widely used hexafluorinated fluororubber was first launched by DuPont under the trade name. The high temperature resistance is better than that of silicone rubber. It has excellent chemical resistance, resistance to most oils and solvents (except ketones and esters), weather resistance and ozone resistance, but poor cold resistance. The general operating temperature range is -~℃. The special formula can withstand low temperatures to -℃.
