1.Kalrez/FKM O-Ring Performance Specifications
Kalrez perfluoroelastomer parts and high-performance FKM(fluoroelastomer)are the gold standards for demanding sealing environments requiring ultra-high chemical80 resistance and thermal stability.KalrezR parts provide low outgassing in vacuum-sealing applications. Perfluorelastomers provide low outgassing in vacuum-sealing applications.These as0240 ring components offer nearly universal chemical resistance and can withstand continuous temperatures up to 275℃(527°F),with some grades reaching 316℃(600°F).Kalrez®has excellent vacuum sealing performance and low outgassing and excellent elastic recovery properties.The material maintains its elastic properties and sealing force even after prolonged exposure to plasma,corrosive process gases,and aggressive chemicals.
2.Vacuum Coating Machine,Leak Detector,and Heat Treatment Furnace Working Conditions
High-tech thermal processing equipment such as vacuum coating machines(PVD/CVD), leak detectors,and heat treatment furnaces operates in environments requiring contamination-free,high-vacuum conditions.In deposition processes like HDPCVD,PECVD,SACVD,Metal CVD,and ALD,seals must resist plasma and aggressive gases without degradation.In vacuum coating machines,any outgassing or breakdown would lead to chamber contamination,affecting thin-film deposition.Kalrez®semiconductor grades are targeted for these applications,offering outstanding thermal stability and low outgassing.In leak detectors,the O-ring provides a hermetic seal essential for detecting microscopic gas escapes.The AS024 size is commonly used in sensor ports,gas inlet manifolds,and vacuum flanges to achieve required base pressures without elastomer vapor release or degradation.

Conclusion
For critical processes in semiconductor fabrication,optical coating,and high-vacuum systems,the as024 o ring made from Kalrez or high-performance FKM provides the necessary integrity to maintain deep vacuum levels.Investing in materials with superior chemical resistance and low outgassing prevents frequent seal replacement and chamber contamination in heat treatment furnaces and leak detection systems.Always ensure your Kalrez o-ring specifications are genuine DuPont product to avoid costly failures in high- vacuum production.
