In laboratory settings, methyl silicone oil is commonly used as the heat carrier in oil baths. Due to its excellent thermal stability, it can maintain stable physical and chemical properties over a wide temperature range and does not rapidly volatilize or decompose during heating, enabling precise temperature control of the reaction system. When conducting organic synthesis reactions that require a constant temperature of 100°C - 150°C, using an oil bath with methyl silicone oil as the heat carrier ensures that the reaction proceeds smoothly at the set temperature, avoiding temperature fluctuations that may affect the reaction yield and product purity, and ensuring the accuracy and reproducibility of the experimental results.
In the industrial production sector, some plastic processing enterprises utilize methyl silicone oil as a heat carrier. Taking the extrusion molding process as an example, methyl silicone oil is used in the circulating heating system to efficiently transfer heat to the barrel of the extruder. The barrel needs to be maintained within a specific temperature range (such as 180°C - 220°C) to allow the plastic raw materials to uniformly melt, enabling smooth extrusion molding. The excellent fluidity and stable heat transfer properties of methyl silicone oil ensure uniform heating of all parts of the barrel, effectively avoiding plastic decomposition due to local overheating or insufficient temperature for complete plasticization, thereby improving the quality and production efficiency of plastic products.
Some precision instruments and equipment also use methyl silicone oil as a heat carrier. In optical coating equipment, to ensure a constant substrate temperature during the coating process, a circulating heat transfer system using methyl silicone oil is employed. Optical coating requires extremely high temperatures, and temperature variations may cause uneven film thickness and poor optical performance. Methyl silicone oil, with its low volatility, chemical stability, and stable heat conduction ability, ensures that the substrate remains at an ideal temperature (such as 80°C - 120°C) during the coating process, providing a stable thermal environment for high-quality optical coating, and helping to produce coated products that meet the requirements of high-precision optical performance.
