PARA-DICHLOROBENZENE Chemical compatibility with O-rings, rubbers, & plastics

Para-dichlorobenzene (PDCB) is an aromatic compound with the chemical formula C6H4Cl2. It is a white crystalline solid with a strong, mothball-like odor, used primarily as a pesticide and deodorant. PDCB is effective against moths, mildew, and mold, making it a common ingredient in mothballs and air fresheners. It is also used as a chemical intermediate in the production of dyes, resins, and other organic compounds. Handling PDCB requires care due to its potential health effects, including respiratory and skin irritation, and its environmental persistence.
