Nylon Chemical Resistance Guide
Are you considering Nylon 6 or Nylon 66 for your next project? While nylon offers excellent resistance to many chemicals, you will want to review our Nylon Chemical Resistance Guide to help you determine if nylon will meet your chemical resistance needs.
Nylon 6 and Nylon 66 resins have outstanding resistance to a wide range of chemicals, especially aliphatic and aromatic hydrocarbons, alkalis, greases, fuels, lubricants, and ketones. This guide is intended to provide some general information on how Nylon resins perform in contact with common chemicals. Testing of molded parts under actual conditions of use is strongly recommended as stresses found in molded parts may negatively influence chemical resistance test results.
