Engineering Disclaimer: Compatibility ratings are provided for reference only. Always verify operating temperatures, concentration limits, and pressure conditions before deploying any material in an active industrial environment.

An industrial chemical compatibility database covering resistance ratings for Polypropylene, Stainless Steel, and Viton across hundreds of acids, solvents, oils, and plating solutions.

Ratings reflect standard industrial testing parameters at ambient temperatures (72°F / 22°C).
