One fluorine rubber rubber O-ring temperature best rubber products

 

Rubber O-ring can withstand high temperatures, more commonly used silicon rubber O-rings and Viton O-rings. The so-called high-temperature O-ring, we must understand the normal use temperature O-ring is the number, select the appropriate O-ring material, depending on the temperature range. Fluorine rubber O-ring temperature limit of 240 degrees, we recommend long-term use at temperatures below 220 degrees, it can be said fluorine rubber O-ring is one of the best rubber products. Silicone rubber O-ring temperature limit of 250 degrees, we recommend long-term use at temperatures below 230 degrees. If the primary is in die-casting mold cooling water seal with the words, with silicone rubber O-ring or fluorine rubber O-rings can all be used. If the oil is not required, you can choose EPDM O-ring, which is EPDM O-ring. Resistant pure natural gas, the general rubber O-rings can be used basically.

 

Viton O-ring rubber material commonly used in high temperature performance is relatively good, the general instantaneous temperature up to 250 degrees, low temperature of -40 degrees instant, but long-term temperature level to decline, long-term high temperature 200 degrees so, long-term resistance to low temperature of about -20 degrees. ZOE's fluorine rubber Viton O-ring in the 250 degree heat resistant when still able to maintain good flexibility and acid resistance does not decrease its resistance when the maximum temperature, the elongation at break can be maintained around 100%, of course, can maintain good wear resistance, oil resistance, in short, good performance fluorine rubber O-rings will not end with the increase of temperature decrease.

 

Viton O-ring seals for the engine, can be long-term work at 200 ?, short-term work at 250 ?, its working life with the same engine repair life, up to 1,000 to 5,000 flight hours (time of 5 to 10 years ); when used in the chemical industry, it can seal inorganic acids, organic solvents and other organic matter; when used in deep oil, can withstand 149 ? and harsh working conditions 420 atmospheres; when used in superheated steam seals can be 160 ~ 170 ? steam medium and long-term work.
