O-Rings in Extreme Environments: Performance and Material Selection

ISMAT produces O-rings or seals for various critical needs and requirements, where extreme temperatures, pressures, and chemically aggressive environments can significantly impact their performance.

1. Temperature Extremes:

• High Temperatures: O-Rings can degrade under high temperatures, leading to hardening, loss of elasticity, and eventual failure. Materials like Perfluoroelastomers (FFKM) are often preferred for high-temperature applications, capable of withstanding temperatures up to 315°C and even higher in some cases.

•   Low Temperatures: At low temperatures, many elastomers can become brittle, compromising their sealing capability. Fluroelastomers (FKM) and Hydrogenated Nitrile (HNBR) perform better at lower temperatures, with some grades suitable for applications as low as -50°C. Flurosilicone (FVMQ) performs better at extremely low temperatures suitable for applications as low as -65°C.

2. High Pressures:

In high-pressure environments, O-Rings must maintain their sealing integrity without extruding or deforming. The choice of Material grades,cross-sectional diameter and material hardness plays a critical role. Harder materials, like FKM, HNBR, often provide better resistance to extrusion, while larger cross-sections can help resist pressure-induced deformation.

3. Chemical Resistance:

Chemically aggressive environments pose a significant challenge. O-Rings must be compatible with various fluids, gases, and chemicals. Fluoroelastomers (FEPM) and Perfluoroelastomers (FFKM) are generally resistant to many chemicals, making them suitable for petroleum products, fuels, Amines and solvents. However, they may not be suitable for steam or certain acids, where alternatives like Ethylene Propylene Diene Monomer (EPDM) might be more effective.
