Certain industries face extreme high-temperature conditions which negatively affect ***material performance*** such as ***electronics manufacturing***, ***automotive engineering***, and ***chemical processing***. Dimethul silicone oil is used as ***a lubricant***, ***heat transfer fluid***, and ***insulation***. Nevertheless, under high temperatures, regular silicone oil may undergo chemical decomposition, become less viscous and/or lose its usefulness, thereby compromising safety and efficiency. With over 12 years of silicone manufacturing experience, and as a member company of Dongguan Cosil Silicone Co., Ltd., Cosil operates within the silicone engineering oil sector. Cosil’s oils withstand high temperatures and extreme conditions, thereby making them ***a key choice*** for over 50 global market players.
The specific dimensions and arrangements of Cosil Dimethyl Silicone Oil allow for superior molecular stability at high temperatures. Cosil's polysiloxane backbone specific construction features methyl groups at the terminal siloxane. The arrangement of the material leads to the construction of siloxane bonds with high levels of bond energy. These bonds are much more difficult to reach lysosomal cleavage than the C-C bonds found in organic oils. The distribution of molecular weights of the Cosil Dimethyl Silicone Oil polymers is specifically designed so the chains of the polymers are of moderate lengths. Oils with short chains are excessively volatile and poorly perform in oils with viscoelastic oils of high molecular weights. Oils with chains optimally sized for the temperature of operation and molecular arrangement perform better in high temperatures with less thermal disturbance. Cosil oils high temperature grade dimethyl silicone oil for example exhibits stability in the viscosity index V150 at 200 degrees centigrade. The same dimethyl silicone oils traditionally would experience more than 30 percent degradation in viscosity value. The oils unique arrangement of molecular substances ensures thermal breakdown is avoided giving the oils peak operation in high temperatures.
More control and more selectivity heighten the high-temperature stability of Cosil's Dimethyl Silicone Oil. Selections of Cosil's core raw materials such as high-purity silica (purity ≥99.9%) and anhydrous methanol from three purification levels of extractive distillation that are able to thermally decompose. During the formulation of the production process, there is a continuous polymerization technology that controls the temperature and pressure precision to not a significant amount of low molecular weight byproducts formed that can lower high-temperature resistance. To Cosil's dimethyl silicone oil, a trace of a special modified silicone compound that is designed to be a high-temperature stabilizer is added to prevent free radical reactions from forming during heating. A testing report states that Cosil's dimethyl silicone oil can run at 250 degree Celsius or longer than 1000 hours before it starts to decompose; a good contrast with other competitors in the market that can only survive that condition for 500 hours. Extreme control is what is needed to say for sure that the product is reliable at high temperatures.
Cosil's dimethyl silicone oil shows reasonably stable characteristics and meets the needs of high temperature environments in several different situations. In the production of automotive engines for one of the top automotive brands, Cosil's dimethyl silicone oil is utilized as a heat transfer fluid in the engine cooling system. It even achieves sufficient heat transfer for temperatures as high as 220 °C and diminishes the cooling system overheating risk. In the production of electronic components, Cosil's dimethyl silicone oil is used as an insulation coating for high power LEDs. It remains for 5 years at an operating temperature of 180 °C in LEDs and does not age, ensuring that insulation performance will not be lost. Another example is a chemical plant that uses Cosil's dimethyl silicone oil as a lubricant for the bearings of high-temperature reaction kettle. The oil withstands a temperature of 240 °C, and the bearing service life is extended 3 times compared to conventional lubricants. In these examples, we see the silicone oil's extraordinary performance in real-world high temperature situations.
In order to guarantee high temperature performance, Cosil subjects its dimethyl silicone oil to rigorous quality testing. The product is ultimately subjected to a battery of high temperature tests, which include thermal aging testing (250° for 1000 hours), testing to assess retention of viscosity, and volatility testing (weight loss is < 3% when held at 200° for 24 hours). Cosil’s laboratory has state of the art thermal analysis equipment, including TGA (Thermogravimetric Analyzer) and DSC (Differential Scanning Calorimeter) which serve to accurately characterize the product’s thermal stability. Furthermore, dimethyl silicone oil from Cosil possesses internationally recognized certificates such as ISO 9001, REACH and RoHS, and as such, complies with international quality and environmental standards. The REACH certificate, for example, attests to the absence of any toxic degradation products that could vent during high temperature exposure. The extent of tests and certificates, especially for these high temperatures, gives customers confidence.
