Ethyl silicone fluid, also known as polydiethylsiloxane and CAS number 63148-61-8, is a colorless to light yellow transparent liquid that plays a versatile role in the industrial field due to its unique physical and chemical properties. Its density range is 0.95-1.05g/cm ³, flash point exceeds 265 ℃, melting point is below -70 ℃, working temperature range covers -60 ℃ to 150 ℃, soluble in organic solvents such as toluene and ether, and can be mixed with petroleum products at will. These characteristics make it an ideal release agent in the molding and processing of rubber and plastic products, and it is widely used in the formulation of instrument oil, hydraulic oil, and special lubricating oil.
In the electrical industry, the dielectric properties of ethyl silicone oil are particularly outstanding. The silicon oxygen bond (- Si-O-Si -) in its molecular structure has high bond energy (121 kcal/mol), endowing the material with excellent thermal stability and weather resistance, and can maintain stable performance in environments ranging from -70 ℃ to 150 ℃ for a long time. This characteristic makes it the preferred insulation material for equipment such as transformers and capacitors, effectively preventing leakage and short circuit risks. In addition, ethyl silicone oil can also be used as a lubricant for precision instruments. Its low surface tension (about 20-21 dynes/cm) and low viscosity temperature coefficient (0.0001-0.0003/℃) ensure that the equipment can operate smoothly even at extreme temperatures.
In the field of rubber processing, ethyl silicone oil significantly improves product quality by improving the flexibility and processing performance of rubber. For example, in tire manufacturing, adding ethyl silicone oil can reduce vulcanization time, improve wear resistance, and reduce energy consumption. The production process uses chloroethane to react with magnesium metal to produce ethyl ethoxysilane, which is then hydrolyzed, condensed, molecularly rearranged, and vacuum distilled to obtain the finished product. The packaging is made of coated iron drums or 10KG plastic drums, which should be moisture-proof, sun protected, and avoid acid-base contact.
