Fluorine Rubber Oil Seal Has Corrosion Resistance
Aug 10, 2017



The installation of fluorine rubber oil seals should pay attention to problems

First of all, we should pay attention to the vertical tolerance of fluorine rubber oil seal and shaft. In general, the perpendicularity tolerance is a variable parameter. Tolerance change basically follows a certain rule, namely: when the shaft diameter is less than or equal to 25mm, FKM Oil Seal the verticality tolerance must be 0.1mm, when the diameter of the shaft between 25 to 28 mm, the verticality tolerance must be controlled in 0.2mm, the last is greater than 80mm a situation, tolerance as far as possible to control within 0.3.

Second, attention should be paid to fixture and press matching use.

Finally, in the installation before the fluorine rubber seal into the oil soaked for a period of time, to remove the surface debris. The other is in the selection of fluorine rubber oil seals when the lip of oil seal is burr and rust, funds spring resilience is good.

Fluorine rubber oil seal high temperature performance fluorine rubber (FPM) of high temperature resistance performance is excellent, at 200-250 degrees Celsius can be long-term work, FKM Oil Seal at 300 degrees can also be a short time to work. The tensile strength and hardness of fluorine rubber decreased obviously with the increase of temperature. The variation of tensile strength and hardness is that, under 150 degrees, it decreases rapidly with the increase of temperature, and at 150-260 degrees, with the increase of temperature, FKM Oil Seal the downward trend is slow.

Fluorine rubber oil seal corrosion resistant performance fluorine rubber (FPM) has excellent corrosion resistance. It has excellent stability against organic liquids, different fuel oils and lubricants, and has good corrosion resistance to most organic acids, hydrocarbons, benzene and toluene.

Fluorine Rubber oil seal compression Permanent deformation performance fluorine rubber (FKM) is used for sealing under high temperature, and the compression deformation performance is the key. Viton-type fluorine rubber is very widely used, FKM Oil Seal and it is inseparable from the improvement of its compression deformation. DuPont in the United States in the 20th century 60-70-year commitment to improve the resistance of fluorine rubber to compression deformation, FKM Oil Seal has achieved remarkable results.

Fluorine rubber oil seal resistance to low-temperature performance fluorine rubber (FKM) can maintain the elastic limit temperature of -15~-20 degree, FKM Oil Seal with the decrease of temperature, its tensile strength becomes bigger, at low temperature appear strong. When the thickness is 2MM, the brittle temperature is 30 degrees and the thickness is 1.87MM, its temperature is 45 degrees, thickness 0.63MM, temperature is-53 degrees, thickness 0.25, temperature is-69 degrees. FKM Oil Seal General fluorine rubber use temperature can be slightly lower than the brittle temperature.

Fluorine rubber oil seals resistant to climate aging and ozone-resistant Vitona natural storage after 10 years of performance is still satisfactory. In the ozone concentration of 0.01% air, the effect of 45 days did not appear obvious cracks. Our common materials: NBR (NBR) fluorine rubber (VITON) EPDM rubber (EPDM) silicone Rubber (VMQ) Neoprene (CR) Styrene-butadiene (SBR) hydride nitrile (HNBR) and so on dozens of kinds of rubber materials, FKM Oil Seal can also provide the shore hardness $number products; Main properties of fluorine rubber
