***The Performance of Hydroxyl-fluoro Silicone Oil in Engine Lubrication (Part One)**
Hydroxyl-fluoro silicone oil performs outstandingly in engine lubrication and has the following remarkable advantages: 1. **Excellent Chemical Resistance and Oil Resistance** The introduction of fluorine-containing groups in hydroxyl-fluoro silicone oil enables it to perform excellently in terms of oil resistance, solvent resistance, and resistance to chemical reagents. This characteristic allows it to remain stable in the complex chemical environment inside the engine and effectively resist the erosion of fuel, lubricating oil, and other chemical substances. 2. **Efficient Lubrication Performance** Hydroxyl-fluoro silicone oil has low surface tension and good lubrication performance, which can form a uniform lubricating film on the surface of engine components, reducing friction and wear. It has a small viscosity-temperature coefficient, and can maintain stable lubrication performance even under high-temperature or low-temperature conditions. 3. **High Temperature Resistance and Antioxidation** The temperature is relatively high during the operation of the engine. The high temperature resistance of hydroxyl-fluoro silicone oil enables it to maintain stable performance under extreme temperatures. At the same time, it has strong antioxidation properties, which can reduce the aging of the oil and the decline of its performance caused by high-temperature oxidation.
