Fluorine Rubber Is More Widely Used In Automotive Sealing Materials Than Ever Before

Edit:Anji Jiahe Fluorourubber Made Products Co.,Ltd      Date:Jun 20, 2017

  Fluorine rubber is more widely used in automotive sealing materials than ever before.

  In order to improve the power of automobile engine, save fuel, and ensure the safety of vehicle driving, new fuel injection system appears. In this system, the car flows from the tank to the engine and then returns to the tank to circulate, and the mixture of gasoline and oxygen produces hydrogen peroxide. Gasoline, which contains hydrogen peroxide, is called "acidic petrol", which softens or hardens a variety of hydrocarbon compounds. and fluorine rubber will not be caused by exposure to acidic gasoline and deterioration of the deterioration.

  Every year, countries in the world enact new regulations on environmental protection. The automobile industry is becoming more and more difficult to meet the requirement that the total hydrocarbon emission of automobiles is restricted by increasingly strict. In the United States, cars must be tested by cobbled (airtight tank evaporation test). Fluorine rubber has excellent barrier to the permeation of hydrocarbon, so it can reduce the permeability of hydrocarbon in the structure of the fuel-oil rubber pipe.

  The product of the automobile fuel system must function normally in the temperature range of the -40. However, fluorine rubber with fluorine content increase in low temperature performance degradation (glass temperature rise), in order to manufacture under the -40 of the normal performance of products, need to improve the cold resistance of fluorine products. Today, the whole fluorine ether rubber has been developed and listed, effectively improving the low-temperature performance of fluorine rubber, but because of the price problem is still difficult to promote.

  The automotive industry is closely concerned about the methanol of fuel, and is eager to carry out the study of FFV (Flexible fuel Vehicle) which may adapt to any fuel, especially the Ffv of rubber parts. When methanol is mixed with gasoline, the volume swelling of fluorine rubber is about 10%. However, as far as methanol is concerned, the volume swelling difference of fluorine rubber is very large because of the different fluorine content. When the fluorine content is high, there is hardly swelling, but with the decrease of fluorine content, the swelling in the low temperature area becomes larger, especially when the fluorine content is 66%, the volume swelling will increase significantly. This is considered to be due to the proximity of the SP value of the methanol bond produced by hydrogen bonding at low temperatures to the polymer with a fluorine content of 66%.

  In a sense, fluorine rubber is also the result of the progress and development of the Times. Although these materials are of high price, but with its excellent wear resistance, oil resistance and reliability, and so on, has a high practical value, therefore, its dosage in the gradual rise is not surprising. The development of fluoride also has great potential and possibilities, and looks forward to the future development of higher value fluoride polymers.
