Chemical Compatibility and Resistance Chart

Miniature diaphragm pumps, vacuum pumps, micro air compressors and solenoid valves are composed of plastics, elastomers and metal components that interact with a wide range of fluid media depending on the application. The selection of materials that comprise the wetted components of a fluidic system needs to be reviewed for compatibility with the gas or liquid media to be employed. Depending on the type and aggressiveness of the media interacting with these components, swelling, reduced life, decreased performance or catastrophic failure could occur. The Hargraves Chemical Compatibility and Resistance Chart should be referenced to properly select materials for specific fluidic applications.
