Comments Off on Chemical Resistance 101: Ensure Your Component Can Resist the Chemicals It’s Exposed to
Prevent degradation to your application with a Chemical Compatibility Guide
Each and every elastomer material — and family of materials — comes with specific capabilities.
Elastomers demonstrate resistance to harmful chemicals and fluids, but they vary greatly in performance depending upon the material in question. It’s crucial to the success of a project to prevent failure or degradation from chemical exposure by choosing an elastomer with the right resistance properties.
For example, both Natural Rubber (NR) and Butyl are classed as General Purpose, Non-Oil-Resistant elastomers. But their performance is very different.
Natural Rubber is resistant to most moderate chemicals, wet or dry, including organic acids, alcohols, ketones and aldehydes. It is generally attacked by strong Acids, fats, oils, greases, and most hydrocarbons.
Butyl, however, resists animal and vegetable oils, greases, and strong and oxidizing chemicals. It is attacked by petroleum solvents, coal tar solvents, and aromatic hydrocarbons.
Having a Chemical Compatibility Guide like CGR’s on file is helpful for breaking out these particular traits so you can choose the proper elastomer more efficiently. The chart can be used to rule out any elastomers with undesirable vulnerabilities for your project, covering information such as:
- Types of elastomers and their ASTM designations
- The chemicals that each elastomer material resists
- The chemicals that degrade the materials
- And more
CGR Products specializes in cutting and fabricating flexible, non-metallic materials into custom parts, shapes, sizes and forms for markets of all kinds. We work with an immense range of materials, including acrylics, adhesives, nitrile, neoprene, polyurethane, and many more.
