NAPHTHALENIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Naphthalenic acid, often referred to as naphthenic acid and commonly represented by the general formula RCOOH, is a group of petroleum derived carboxylic acids used as intermediates in the production of resins, metal naphthenates, dyes, and specialty chemicals. These compounds are widely used in industrial processing and chemical manufacturing. In systems where they contact O-rings, rubber seals, gaskets, and plastic components, compatibility should be evaluated to prevent swelling or degradation of sealing materials. Proper storage, ventilation, safe handling procedures, and appropriate PPE are recommended to ensure safe operation.
