从China供应商批发进口274#Vacuum Diffusion Pump Oil Equal To Dc704 — FOB条款

274# vacuum diffusion pump oil, equivalent to Dow Corning 704 and HIVAC F-4, is a clear, single-component silicone fluid supplied by Singshine Silicones Co., Ltd. It is chemically classified as tetramethyltetra-phenyltrisiloxane, designed for high-vacuum applications. The oil achieves untrapped vacuum levels of 10⁻⁷ to 10⁻⁸ torr and trapped levels down to 10⁻¹¹ torr, making it suitable for demanding laboratory and industrial systems.

The oil’s physical properties include a viscosity of 38 ± 3 mm²/s at 25°C, a refractive index of 1.5500 to 1.5600, and a specific gravity of 1.050 to 1.080. It has a high flash point of at least 210°C and a condensation point of -35°C, ensuring stable performance across a wide temperature range. The saturated vapor pressure is a maximum of 6.65 × 10⁻⁸ Pa, which is critical for maintaining ultra-high vacuum conditions.

This product is primarily used in vacuum diffusion pumps for semiconductor manufacturing, research laboratories, and analytical instruments. Singshine Silicones Co., Ltd. packages the oil in 200 kg iron drums or 25/50 kg plastic drums. Buyers should confirm packaging options, lead times, and incoterms, as these are not detailed in the listing.

Singshine Silicones Co., Ltd. is located in Room 1409, Bengbu Building, Huaihai Road, Bengbu, Anhui Province, China. The company specializes in silicone-based products, including high-performance fluids for industrial applications. Its product line includes vacuum diffusion pump oils equivalent to internationally recognized brands like Dow Corning 704.

The supplier holds an imported tier classification and a harbor trust tier, but no response rate, average response time, or certifications are provided in the listing. Buyers should directly confirm the company’s production capabilities, quality control processes, and compliance with industry standards for vacuum pump oils.
