275# silicone oil for vacuum diffusion pump is a colorless, transparent oily fluid with the molecular formula CH3(C6H5)2SiO(CH3)2SiOSi(C6H5)2CH3, designed for super high vacuum environments. It achieves an ultimate vacuum of 5×10⁻⁹ and maintains a viscosity of 165 - 185 mm²/s at 25°C, with a refractive index of 1.5765 - 1.5785 at the same temperature. The oil offers a flash point of 243°C and a freezing point no higher than -14°C, ensuring stable performance across a broad temperature range.
This silicone oil is formulated with a minimum 99% content purity, providing excellent resistance to high temperatures, oxidation, and radiation. Typical for dimethyl phenyl silicone fluids, it retains low volatility under vacuum conditions, which is critical for diffusion pump applications. The oil’s chemical structure, incorporating phenyl groups, enhances thermal stability compared to standard dimethyl silicones, making it suitable for demanding industrial and laboratory use.
Common applications include high vacuum systems, electrical insulation in high voltage equipment, coatings for vacuum chambers, particle accelerators, electron microscopes, and display manufacturing. Buyers typically source this oil in bulk for semiconductor fabrication, research laboratories, and industrial vacuum processes. Confirm packaging, lead times, and incoterms directly with Yangzhou Chenhua New Material Co., Ltd, as these are not specified in the listing.

Sourcing 275# silicone oil for vacuum diffusion pump from Yangzhou Chenhua New Material Co., Ltd - China Import Guide
Before ordering, verify the oil’s compatibility with your vacuum system’s design specifications, particularly the pump’s temperature range and material construction. Request a technical data sheet and certificate of analysis to confirm the batch-specific properties such as viscosity, refractive index, and vapor pressure match your requirements.
Logistics for this product require attention to temperature control during transport, as the oil’s performance can degrade if exposed to extreme heat or cold. Confirm the incoterms (e.g., FOB or CIF) with Yangzhou Chenhua New Material Co., Ltd, and discuss payment terms such as L/C or T/T. Lead times may vary, so clarify production and shipping schedules upfront.
Quality checks should include testing the oil’s viscosity and refractive index upon receipt to ensure they fall within the specified ranges. Inspect the packaging for leaks or contamination, and request documentation such as an MSDS and compliance certificates for industry standards. For critical applications, consider third-party testing to validate the oil’s performance in your specific vacuum environment.
