Pyromellitic Acid CAS 89-05-4

Pyromellitic Acid is a white crystalline powder, soluble in hot water and polar solvents.As an important organic synthesis intermediate, it is mainly used in the production of high temperature resistant materials (such as polyimide resin), insulating coatings for electronic components and special adhesives.Its high thermal stability and tetrafunctional group properties give the material excellent performance, but the operation should avoid inhalation of dust, which is irritating to the skin and mucous membranes.
