With the continuous enhancement of the demand for equipment's all-weather adaptability and extreme heat management in high-end manufacturing, the high and low temperature limit performance of working media has become a key indicator for measuring system reliability. The company, Anhui Aiyota Silicone Oil Co., Ltd., has launched the product high-temperature silicone oil 255A. As a modified phenyl silicone oil with high phenyl content, it has achieved significant breakthroughs in terms of temperature resistance range, thermal oxidation stability and radiation resistance, providing a new functional fluid solution for aerospace, nuclear energy industry, deep space exploration and special lubrication fields. 
Breakthrough wide temperature range working capability 
The most significant technical advantage of the product's high-temperature resistant silicone oil 255A lies in its extremely wide operating temperature range, which can operate stably for a long time within a temperature range of minus seventy degrees Celsius to three hundred and twenty degrees Celsius. This temperature coverage capability far exceeds that of ordinary phenyl silicone oil, enabling it to simultaneously meet the low-temperature start-up requirements of polar cold regions and the continuous lubrication and heat transfer tasks of extreme hot areas such as aircraft engine compartments and high-temperature reactors. Its freezing point is lower than minus seventy degrees Celsius, ensuring good fluidity and pumping performance in extremely cold environments; its flash point is not lower than three hundred and five degrees Celsius, providing sufficient safety guarantee for the safe operation at high temperatures. 
Outstanding thermal stability and antioxidant properties 
As a modified phenolic silicone oil with high phenolic content, the product "High Temperature Silicone Oil 255A" introduces a high proportion of phenyl groups into its molecular structure, significantly enhancing the thermal stability and anti-thermal oxidation ability of the polymer chain. Under long-term high-temperature exposure, this product can effectively inhibit the cyclization degradation of the silicon-oxygen main chain and the oxidation cross-linking of the side chains, maintaining the stability of viscosity and chemical inertness. This enables it to maintain reliable lubricating film strength and dielectric properties at temperatures above 300 degrees Celsius, and is suitable for harsh environments such as high-temperature bearings, hot roller drives, and closed-loop thermal systems. 
Excellent lubricity and damping properties 
Product 255A high-temperature silicone oil combines excellent lubrication properties with moderate compressibility, and can be used as the base oil for high-temperature lubricants and greases. In precision instruments, high-speed bearings, and micro-motors, it can effectively reduce the friction coefficient, minimize wear, and provide stable damping effects. Its inherent chemical inertness ensures that it will not corrode metal components, and it is compatible with most engineering plastics and sealing materials, avoiding leakage or sealing failure issues caused by medium erosion. 
Radiation resistance and hydrolytic stability 
This product has good stability in water and is not prone to hydrolysis and deterioration in humid environments. It also possesses excellent radiation resistance and is suitable for use in hydraulic and lubrication systems around nuclear facilities. Its refractive index range is between 1.46 and 1.55. It can be adjusted according to different formula requirements to meet the light transmittance requirements of specific optical or detection equipment for the medium. 
Widely applicable fields 
Based on the above comprehensive performance, the product high-temperature silicone oil 255A can be widely applied in the following fields: as the base oil for high-temperature lubricating oil for aircraft engines and turbine machinery; used as the hydraulic buffer medium for the control rod drive mechanism and valve actuator of nuclear power plants; as the radiation-resistant temperature control fluid for the attitude control propulsion system of deep space probes; serving as a heat carrier in high-temperature heat rollers, calendering machines and injection molding equipment; and also can be formulated into long-lasting high-temperature lubricating grease, used for the high-temperature bearings and chains in the metallurgy, ceramics, glass and automotive manufacturing industries. 
Packaging and Storage Instructions 
The product, high-temperature resistant silicone oil 255A, is available in three packaging sizes: 25 kilograms plastic drums, 50 kilograms plastic drums, and 200 kilograms iron drums. These sizes are suitable for users of different scales, facilitating their purchase and use. The product should be stored in clean, dry containers, in a well-ventilated and dry warehouse, and transported as non-hazardous goods. Once unopened and under the storage conditions that meet the requirements, its shelf life is three years. 
The manufacturer stated that with the continuous growth of domestic demand for the domestication and substitution of materials for extreme environments, the product "High Temperature Silicone Oil 255A" with its outstanding wide temperature range performance and comprehensive reliability will provide strong support for the independent guarantee of China's high-end equipment.
