④ molecular structure and properties of fluorine rubber O-ring: fluorine-containing molecules within the rubber fluorine rubber seals, according to the fluorine content (ie monomer structure) and there are various types. Six series of fluorinated Viton currently the most widely used first by DuPont to "Viton" tradename listed. High temperature resistance than silicone rubber white fluorine rubber seals, have excellent chemical resistance, resistance to most oils and solvents (ketones, esters excluded), weather resistance and ozone resistance; cold resistance is relatively poor, generally used temperature range of -20 ~ 250 ℃. Specially formulated to be low temperature -40 ℃. Viton has excellent mechanical properties. 26 fluorine rubber generally fit between the high-temperature strength between 10 ~ 20MPa fluorine rubber seals, elongation at break of between 150 to 350%, tear strength at 3 ~ 4KN / m. 23 fluorine rubber strength between 15.0 ~ 25MPa fluorine rubber ring pad, elongation of 200% to 600%, tear strength between 2 ~ 7MPa. Generally, fluorine rubber compression at elevated temperature a large permanent deformation, but if the conditions are the same, as the same time is compressed from 150 ℃ under permanent deformation of view, butyl and neoprene than 26 fluorine rubber should be large, 26 fluorine rubber compression 200 ℃ × 24 hours is equivalent deformation butadiene rubber at 150 ℃ × 24 hours compression. y-type fluorine rubber seals fluorine rubber seals _ _ East morning plastic provided by Junan East morning plastic products co.
