Volumetric Swell vs. Hardness Shift in Elastomers

Summary Why Swell and Hardness Matter in Seal Performance When an elastomer seal is exposed to fluids over time, two material-level changes largely determine its long-term reliability: volumetric swell and hardness shift. These parameters capture how the seal’s size and stiffness evolve due to chemical exposure. Excessive swell or a significant change in hardness can […]

O-Ring Materials for Chemical Resistance

Summary Why Chemical Compatibility Matters for O-Rings An o-ring’s effectiveness heavily depends on using a material that can withstand the chemicals it contacts. Selecting the wrong material for a given chemical environment can lead to premature failure due to chemical degradation, causing the seal to swell, crack, or shrink and resulting in leaks. Such failures […]

The Pressure Test: AFLAS® Under Extremes

Summary Why AFLAS®? Built for the Extremes In high-performance sealing environments, material selection is critical to withstand environmental stressors. System exposure to high heat, aggressive chemicals, and steam requires a material that can endure these conditions without degrading, swelling, or hardening over time.  AFLAS® offers a level of durability that general-purpose elastomers can’t match. Classified […]

温度对 O 形圈的影响

Summary Introduction O-rings are widely used sealing components in industrial systems, preventing fluid or gas leakage between mating surfaces. Their performance depends heavily on the properties of the elastomer material, which must maintain elasticity, sealing force, and chemical stability during operation. Temperature is one of the most influential factors affecting o-ring behavior. Changes in temperature […]
