Broad chemical-service screening including aromatic/chlorinated hydrocarbons, ketones, esters, ethers, polar solvents, organic acids, steam and vacuum.
Review before use with
Fluorinated refrigerants and temperature-critical service require exact-compound review.
Family-level screening, not an approval of a specific compound. Screen a chemical or ask for a material check.
