LicenceChemical compatibility ratings are factual engineering data published by manufacturers and distributors as free technical resources. Each record quotes a short attributed span from a publicly available chart and links back. Facts are not copyrightable (Feist, 1991).

About this data

The compatibility rating of a chemical against thirteen common elastomer families, as published in an industry chemical resistance chart. Each record is one chemical carrying its rating for Nitrile (NBR), EPDM, Neoprene (CR), SBR, Silicone (VMQ), Butyl (IIR), Polyacrylate (ACM), Hypalon (CSM), Viton (FKM), Polyurethane (AU/EU), Fluorosilicone (FVMQ), Aflas (TFE/P), and Kalrez (FFKM). Answers 'is Viton compatible with acetone', 'which elastomer resists sulfuric acid', 'can I use EPDM with gasoline', and 'Nitrile vs EPDM for sodium hydroxide'. Ratings use a 1-4 scale: 1 = Satisfactory, 2 = Fair, 3 = Doubtful, 4 = Unsatisfactory, X = Insufficient Data.

Showing the first 400 of 2,086 records. Every record has its own page, with its source and the quoted line that states it; these list the rest.

Records 1–400Abietic Acid … Calcium Naphthenate
Records 401–800Calcium Nitrate … Ethylene Dichloride
Records 801–1,200Ethylene Glycol … Methyl Carbonate
Records 1,201–1,600Methyl Cellosolve … Potassium Salts

Records 2,001–2,086Turbine Oil … Zirconium Nitrate

Where this came from

Every record above links the page it was taken from and quotes the sentence that states it. These are the 6 sources this dataset was assembled from.

Machine-readable

data.jsonThe whole dataset — every record with its source URL and source quote.
Open Knowledge Format bundleOne JSON object per line — every record's frontmatter and quoted span exactly as it is held here, in one fetch.
data.csvThe same records as one flat table, for a spreadsheet or a dataframe. The last four columns are the source URL, the quoted sentence it was read from, the date we last checked it, and which columns are our reading rather than the page's words.
How this is made and checkedWhat "verified against source" does and does not mean.

From your own code

Same records, same quotes, without scraping the page: refsource is on PyPI and npm. Each value comes back carrying the URL it was read from and the sentence on that page that states it — .source and .quote sit on the value itself rather than in a side channel, so the checking step is available instead of skipped.

pip install refsource
refsource lookup chemical-elastomer-material-compatibility chemical="Abietic Acid"

npx -y refsource lookup chemical-elastomer-material-compatibility chemical="Abietic Acid"

Set your AI assistant up to use this

Two files and no account. Put this in .mcp.json at the root of your project — Claude Code, Cursor, Windsurf, VS Code and Codex all read that file — and your assistant can look this dataset up instead of recalling it. The server is remote, keyless and read-only.

{
  "mcpServers": {
    "referencesource": {
      "type": "http",
      "url": "https://referencesource.org/mcp"
    }
  }
}

Add to Cursor · or, on the command line: claude mcp add --transport http referencesource https://referencesource.org/mcp --scope project

Then one line in the project's CLAUDE.md or AGENTS.md, so the assistant knows when to reach for it:

When a question needs "Chemical resistance ratings for common elastomers", call the referencesource MCP server at https://referencesource.org/mcp (tool `search_records`, dataset_slug `chemical-elastomer-material-compatibility`) instead of answering from memory — every record it returns carries its source URL and a verbatim quote from that page.

Licence. Chemical compatibility ratings are factual engineering data published by manufacturers and distributors as free technical resources. Each record quotes a short attributed span from a publicly available chart and links back. Facts are not copyrightable (Feist, 1991).
