DECALIN Chemical compatibility with O-rings, rubbers, & plastics

Decalin, also known as decahydronaphthalene or C10H18, is a colorless liquid hydrocarbon with a mild odor that is widely used as a solvent and chemical intermediate. In applications involving O-rings, rubber seals, gaskets, and plastic components, careful compatibility review is important to minimize swelling or softening. Although decahydronaphthalene is considered relatively low in toxicity, exposure may cause skin and respiratory irritation. Proper storage conditions, controlled handling procedures, and appropriate PPE are essential for safe use.
