Methyl Fluorosilicone Oil is a fluorine-modified polysiloxane fluid featuring a siloxane backbone with methyl and fluoroalkyl side groups.
It combines the inherent advantages of silicone oils—such as wide service temperature range and excellent flexibility—with significantly improved resistance to fuels, oils, and aggressive chemicals.
This product is designed for applications requiring reliable lubrication, sealing, damping, or surface performance under harsh chemical and thermal environments.
