Permeability of Elastomers and Plastics

Learn about the permeability of elastomers and plastics in this comprehensive guide. Discover how different materials allow gases and liquids to pass through, and how factors like temperature, pressure, and material composition impact permeability. Whether you're designing O-rings, seals, gaskets, or other components, understanding permeability is essential for ensuring optimal performance in your applications.


Whatever your O-ring and gasket material requirements may be, Canyon Components can support you! If you can't find the O-ring material you need, or if you require something custom, feel free to get in touch with our engineers.
