DOW CORNING -550 Chemical compatibility with O-rings, rubbers, & plastics

Dow Corning 550 silicone fluid, also known as DC 550 phenylmethyl silicone oil, is a high performance silicone fluid widely used in industrial lubrication, heat transfer, and thermal stability applications. This fluid offers excellent oxidation resistance and consistent viscosity across a broad temperature range. In systems containing O-rings, rubber seals, gaskets, and plastic components, chemical compatibility should be evaluated to prevent swelling or degradation of certain rubber materials. Proper handling, storage, and appropriate protective practices are recommended to ensure safe use.
