In the process of continuously developing towards extreme environmental adaptability and high reliability in fields such as aerospace, polar research, precision instruments, and chemical production, special silicone oil with superior low-temperature resistance, excellent lubricity, and wide compatibility is becoming a key material to break through the technical bottlenecks in low-temperature conditions. Our company's product, ethyl silicone oil 2056 PES, as a mixture of polydiethylsiloxane, demonstrates significant application value in extremely cold regions for equipment lubrication, heat transfer in hydraulic systems, chemical demolding, and cosmetic formulation, providing high-performance special lubricating oil solutions for various industry customers.


I. Core Physical and Chemical Properties and Structural Advantages


Product ethyl silicone oil 2056 PES is a colorless to light yellow liquid, available in two viscosity specifications: PES-1 and PES-2. PES-1 has a viscosity of 34 to 40 centipoises at 25 degrees Celsius, with a flash point above 170 degrees Celsius and a density of 0.95 to 0.98 grams per cubic centimeter; PES-2 has a viscosity of 180 to 280 centipoises, with a flash point above 265 degrees Celsius and a density of 0.99 to 1.02 grams per cubic centimeter. Both products have a refractive index of 1.44 and a freezing point below minus one hundred degrees Celsius, with an acid value of less than 0.1 milligrams of potassium hydroxide per gram.


The core structural advantage of this product stems from its unique molecular design. Unlike ordinary methyl silicone oil, the side chain of ethyl silicone oil is substituted with ethyl, providing a longer carbon chain that gives the molecule greater flexibility, effectively inhibiting low-temperature crystallization, and reducing its freezing point to below minus one hundred degrees Celsius. This characteristic enables it to maintain good liquid flowability and pumping capacity in extremely low-temperature environments, solving industry pain points such as equipment lubrication and hydraulic transmission stalling in extreme low-temperature conditions.


II. Core Performance Advantages


Product ethyl silicone oil 2056 PES, with its unique molecular structure, exhibits the following core performance advantages in various application systems:


Super low-temperature resistance. The product has a freezing point below minus one hundred degrees Celsius and can operate stably within a wide temperature range from minus one hundred thirty degrees Celsius to two hundred and fifty degrees Celsius above zero, far exceeding the minimum working temperature range of ordinary methyl silicone oil.


Complete compatibility with mineral oil and synthetic oil. Unlike ordinary methyl silicone oil, which can only partially dissolve, this product is completely miscible with mineral oil and synthetic oil, and can be directly integrated into the existing industrial system without large-scale equipment modification.


Excellent lubrication performance and chemical inertness. The product has excellent lubrication performance and is chemically inert towards structural and functional materials such as metals, alloys, plastics, and rubber, with no corrosive effect. Its safety is outstanding.


Excellent dielectric properties. The product has excellent electrical insulation properties and maintains stable dielectric performance in both high and low temperatures, suitable for instruments and liquids in electromechanical applications.
