Viton® (FKM) O-Rings: Properties, Grades, and Industrial Applications

Summary What Are Viton® O-Rings? Viton® (FKM) o-rings are fluoropolymer elastomer seals engineered for extreme service conditions where standard rubber compounds fail. Developed in the late 1950s by DuPont, Viton® is a registered brand name for FKM — fluoroelastomer — a synthetic rubber defined by its high fluorine content. That fluorine content is the source […]

PFAS 化学品及其对弹性体的影响

Summary Overview PFAS (per- and polyfluoroalkyl) are synthetic chemicals widely used in various industrial and consumer products across multiple sectors. However, concerns about their effects on human health and the environment have sparked debates and regulatory actions worldwide. This article explores the uses of PFAS chemicals, regulatory efforts in the United States, Europe, and Canada, […]

热膨胀与密封性能

摘要 热膨胀简介 热膨胀是指材料在暴露于温度升高时如何膨胀。当密封件因温度波动而发生尺寸变化时，可能会出现泄漏、挤压或故障等问题，因此热膨胀是材料选择和密封件设计过程中必不可少的考虑因素。了解热膨胀如何影响密封件[…]

变形、应力松弛和反弹

Summary Introduction Elastomer seals are critical components in many industrial applications, providing the sealing force needed to prevent leaks and maintain pressure between mating surfaces. These seals must perform reliably under a range of operating conditions, including mechanical compression, temperature variation, and chemical exposure. Seal performance depends heavily on how elastomer materials respond to deformation […]
