TMC-705 DIFFUSION PUMP FLUID
TMC-705 is a methylphenyl silicone fluid with superior resistance to oxidation, heat, and chemicals. TMC-705 is used for vacuum pumps applications and enables prolonged, stable operation. PRODUCT FEATURES Superior oxidation, heat, and chemical resistance. Does not crack under heat or intake gas, unlike petroleum and fatty acid ester pump oils. Does not emit oxidation gas. Does not produce acid, tar, pitch, or other substances when vacuum is broken during heating. Enables prolonged and stable operation of vacuum pumps. APPLICATIONS High-vacuum oil diffusion pump applications.
