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 830+ 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.
Every rating on this site is read directly from the Bürkle spreadsheet. The spreadsheet has 1,651 rows. 661 of them are synonyms that point at another row and carry no ratings of their own, so the site counts 990 rows with data, covering 835 chemicals.
In September 2026 the 20 °C ratings of 27 common chemicals were compared with other published charts: 389 chemical and material combinations. Most agreed within one grade. Where at least two independent sources rate a material clearly worse than the Bürkle list does, the value is either corrected or marked as disputed, and the page gives the reason and the references. The rest of the data has not been checked this way.
Source values use the scale 1 (very good) to 4 (not resistant).
We use a simple A-D rating scale:
This tool is for guidance only.
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.
