Ethyl silicone oil is a kind of organic silicon material with excellent high and low temperature resistance, chemical stability, insulation and lubrication properties. It is widely used in the automotive industry. The following are its main application areas and specific functions:
1. Lubrication and protection
Engine and transmission system:
Ethyl silicone oil can be used as a lubricant additive to improve the high temperature resistance and oxidation resistance of the base oil and reduce the wear of the engine at high temperature. Its low volatility can also reduce lubricant consumption.
Rubber and plastic parts protection:
Used to protect rubber seals, plastic pipes, etc., prevent aging and cracking, and extend service life.
2. Damping and shock absorption
Suspension system and shock absorber:
As a damping medium, the high viscosity-temperature characteristics of ethyl silicone oil enable it to maintain stable damping performance in a wide temperature range, improving the smoothness and stability of vehicle driving.
Noise reduction application:
Damping grease used for interior parts such as doors and dashboards to reduce vibration and noise transmission.
3. Electrical and electronic systems
Insulation and protective coatings:
The excellent insulation properties of ethyl silicone oil can be used for protective coatings of wiring harnesses and connectors to prevent moisture and corrosion.
Thermal conductive materials:
As a heat dissipation medium in some electronic components, it improves the efficiency of heat conduction.
4. Demolding and manufacturing process
Parts manufacturing:
As a demolding agent used in the molding process of plastic, rubber or metal die-casting parts to improve production efficiency and finished product quality.
Surface treatment:
Used for mold surface coating to reduce friction and wear.
5. Special functional materials
High temperature resistant sealant:
Ethyl silicone oil-based sealant can be used in high temperature areas such as engine compartments and exhaust pipes to provide long-term and reliable sealing.
Optical and display components:
As an anti-fog or waterproof coating in vehicle-mounted screens or camera modules to maintain stable optical performance.
Summary of advantages
Temperature adaptability: It can work stably in the range of -60℃ to 250℃, suitable for extreme working conditions.
Chemical inertness: It does not react with most metals, plastics and rubbers, extending the life of components.
Environmental protection: Some products meet the requirements of low VOC, reducing environmental pollution.
Typical application cases
Suspension system of high-end models: magnetorheological dampers based on ethyl silicone oil are used to adjust the suspension hardness in real time.
New energy vehicle battery pack: As a heat transfer medium for thermal management systems, it improves battery safety and life.
With its unique performance advantages, ethyl silicone oil has become one of the indispensable functional materials in the modern automotive industry.
