Product Simple Attributes
Shin-Etsu HIVAC-F4 is a high-performance methylphenyl silicone oil designed for high vacuum diffusion pumps. It features excellent heat resistance, oxidation resistance, and chemical stability, maintaining stable performance in high vacuum environments.
Product Introduction
Shin-Etsu HIVAC-F4 is a synthetic oil formulated from refined silicone oil and micro-powdered silica. It offers excellent heat resistance, oxidation stability, and chemical reaction stability, making it suitable for sealing and lubricating high vacuum diffusion pumps. HIVAC-F4 can achieve a vacuum level of 10⁻⁶ Torr, and with a liquid nitrogen trap, the vacuum level can be further increased to 10⁻¹² Torr. This silicone oil does not produce oxidation gases or acidic substances when heated, ensuring stable operation of vacuum pumps over the long term.
Product Special Attributes
The special attributes of Shin-Etsu HIVAC-F4 include its superior heat resistance and chemical stability. It can maintain stable performance at temperatures up to 300°C, without the thermal cracking issues associated with petroleum-based pump oils. Additionally, HIVAC-F4 does not generate oxidation gases or produce acid, tar, pitch, or other substances when the vacuum is broken during heating, ensuring stable operation of vacuum pumps even after long-term use. Its moderate viscosity and good flowability allow it to form an even oil film within the pump chamber, effectively reducing friction and wear.
Application scenarios
Shin-Etsu HIVAC-F4 is widely used for lubrication and sealing in high vacuum diffusion pumps, suitable for electronic device manufacturing, scientific instruments, semiconductor production, and other fields requiring high vacuum environments. It is also used for sealing various high vacuum devices, such as vacuum coating machines and vacuum drying ovens, ensuring stable operation of equipment under high vacuum conditions.
