A free, modern tool for finding compatible materials for chemical storage and handling.
Choosing the wrong material for chemical storage can lead to container failure, leaks, environmental damage, and workplace injuries. Yet finding reliable compatibility data has traditionally meant digging through scattered PDF charts or expensive proprietary databases.
ChemicalResistance.org was created to change that. We've built a fast, searchable database covering 1,650+ chemicals and 24 materials — completely free, with no registration required.
Selecting materials for process equipment, piping, and storage tanks.
Ensuring proper secondary containment and spill response equipment.
Choosing compatible seals, gaskets, and replacement parts.
Specifying the right drums, IBCs, and storage containers.
Ratings at both 20°C and 50°C where available.
Our chemical resistance data is based on the comprehensive compatibility charts published by Bürkle GmbH, a German manufacturer of laboratory and industrial equipment with decades of expertise in chemical handling.
Important: Bürkle generously allows this data to be "freely passed on and copied" with attribution. We maintain this attribution throughout our site and encourage users to visit buerkle.de for their original materials.
We use a simple A-D rating scale:

Chemical resistance depends on many factors beyond what a single database can capture:
Always verify compatibility with your equipment manufacturer and conduct testing for critical applications. We accept no liability for decisions made based on this information.
