?High temperature resistance, chemical solvents Hydraulic O-rings

??With industrial development of reliability, safety and other requirements on the rise, high temperature, high friction, and other harsh working environments, the hydraulic O-ring material in continuous improvement, high temperature resistance, chemical materials increasingly solvent update FKM has the characteristics of high temperature, oil resistant to many chemicals and erosion. Viton O-ring in a hydraulic amount has also increased rapidly.

??High temperature resistance than silicone rubber, has excellent chemical resistance, resistance to most oils and solvents (ketones, esters, except), weather resistance and ozone resistance; cold is relatively poor, the general temperature range of -20 ~ 250 ?. Specially formulated to be low temperature -40 ?.

??26-41 fluorine rubber O-ring hydraulic long-term use at 250 ?, 300 ? under short-term use; 246 fluorine rubber O-ring hydraulic heat better than 26-41. After 300 ? × 100 properties 26-41 Xiaoshi air heat aging after 300 ? × 100-hour hotline 246-type air aging properties equivalent to its elongation can be maintained at around 100%, the hardness of 90 to 95 degrees. After the 246-type after hot air aging at 350 ? 16 hours to maintain a good elasticity, hot air aging at 400 ? for 110 minutes after good elasticity, hot air aging at 400 ? for 110 minutes, spray containing carbon black, thermal carbon blacks or carbon fibers the rubber elongation increased by about 1/2 ~ 1/3, the intensity decreased about 1/2, still maintain good flexibility. 23-11 Hydraulic fluorine rubber O-rings can be long-term use at 200 ?, 250 ? under short-term use.

??The main characteristics of the hydraulic fluorine rubber O-rings are temperature and chemical resistant, and have a good anti-aging and anti-ozone performance, and very low permeability tolerance. Even in very poor working conditions, there is still a very good wear resistance. Viton +200 degrees or less able to withstand operating temperatures can be allowed to run a short time without the oil situation.
