Thanks to its outstanding thermal stability and radiation resistance, phenyl silicone oil is increasingly used as a preferred diffusion pump oil in high vacuum systems. Compared to conventional silicone oils, phenyl silicone oil delivers lower vapor pressure and superior oxidation resistance, maintaining consistent performance even during extended operation. IOTA’s high-purity phenyl silicone oils are widely adopted by vacuum equipment manufacturers, offering efficient and stable pumping solutions for metallurgy, electronics, and aerospace sectors.
