1.FKM(Viton)O-Ring Performance Specifications
FKM is a family of fluorocarbon-based fluoroelastomer materials defined by the ASTM D1418 standard.Fluorocarbon(FKM)has excellent resistance to high temperatures,ozone, oxygen,mineral oil,synthetic hydraulic fluids,fuels,aromatics and many organic solvents and chemicals.Viton®o-ring's temperature resistance range is one of its most notable attributes,with the capability to endure extremes from-15°F(-26℃)to+400 F(+205℃),and even higher for shorter periods.Standard FKM O-ring temperature ranges are from-15°F to 40O°F.Depending on the grade the working temperature range is considered to be-26℃ to+205°/230℃(-15°F to +400°/440°F).Fluorocarbon elastomers have grown to major importance in the sealing industry due to its wide range of chemical compatibility,temperature range,low compression set,and excellent aging characteristics. These fkm o ring components provide outstanding performance over a broad thermal range and excellent resistance to aging and ozone.FKM offers superior resistance to oils,fuels, and a wide range of chemicals,making them ideal for demanding sealing applications.
2.Industrial Robots,Manipulators,and AGV Working Conditions
In modern automation,industrial robots,manipulators,and automated guided vehicles (AGVs)rely on high-precision joints and actuators that often operate in continuous cycles where internal friction generates significant heat.In harsh environments such as chemical processing or high-temperature applications,FKM seals protect internal components from aggressive chemicals,fumes,and thermal stress.High-performance seals are essential for extending the life of robotic joints,actuators,and automated systems.In industrial robotics,seals and O-rings play a crucial role in ensuring smooth and reliable operation, preventing leaks and keeping contaminants out.Specialized sealing solutions enhance the efficiency and dependability of automated guided vehicles.FKM O-rings are frequently used in pneumatic systems,grippers,and housing seals to maintain airtight integrity and prevent leakage of specialized lubricants,which is critical for precision movements in robotic arms and mobile platforms.
