Naphthalene Balls

Whatsapp Order

Napthalene Balls are solid, crystalline balls made primarily of naphthalene, a white, volatile, aromatic hydrocarbon derived from coal tar or petroleum refining. Known for their strong, distinctive odor, naphthalene balls are widely used as moth repellents and deodorizing agents. Due to their sublimation property, they slowly vaporize at room temperature, releasing fumes that are toxic to moths and insects. They find broad applications in household pest control, industrial storage protection, and chemical manufacturing.
