With its unique chemical structure and versatility, silicone silicone oil has shown significant performance advantages in the field of automotive care, especially in the field of new energy vehicles. It has broad application prospects.The following three aspects are described in detail from the performance advantages, application areas and future prospects.

1. Performance advantages
High temperature resistance
The main chain of silicone silicone oil is a “-Si-O-Si-” structure, with large bond energy and high stability, which makes it perform well in high temperature environments.Ordinary silicone silicone oil has a heat-resistant temperature range of 200~250°C, and phenyl silicone can withstand higher temperatures.Even in high-temperature environments such as the engine compartment, it is not easy to decompose or evaporate, ensuring stable lubrication and protection performance.For example, in high-temperature tests, high-quality silicone silicone oils can be maintained without gel for 1000 hours at 250°C and 48 hours without gel at 300°C. The quality loss rate is extremely low.

Chemical stability
Silicone silicone oil has a high tolerance to acids, alkalis and other chemicals.The silicon-oxygen bond (Si-O) in its molecular structure gives it chemical inertness, and it exhibits good stability to water, air, oxygen, various metals, plastics and other materials at room temperature.Even in contact with concentrated acids and alkalis, silicone oils with high alkane groups and phenyl groups can maintain relative stability and are not easy to react, thereby protecting automotive parts from corrosion.

Environmental protection
Silicone silicone oil is non-toxic and harmless, and meets environmental protection requirements.Its odorless and non-volatile properties make it widely used in automotive interior and exterior care products, and it will not cause harm to the environment and the human body.With the increasingly stringent environmental regulations, this advantage makes it more competitive in the field of automotive care.

Wide temperature application range
Compared with ordinary lubricants, silicone silicone oils have a wider temperature range.Its viscosity is less dependent on temperature, and the viscosity changes less in the temperature range of -60~250°C.For example, the viscosity of polymethylsiloxane increases only to 7 times at -30°C, while Standard Petroleum increases to 1800 times.This allows silicone silicone oils to maintain stable lubricating properties under extreme high or low temperature environments and are suitable for various climatic conditions.

Excellent weather resistance and elasticity
The intermolecular force of silicone silicone oil is small, and it has good weather resistance and elasticity.After long-term use, it can still maintain a good sealing effect and prevent the penetration of moisture, dust and noise.This characteristic makes it widely used in the field of automotive sealants to ensure the reliability of long-term use.

2.the application field
Car polishing agent
Silicone silicone oil is one of the key components of automotive polishes.It can form a smooth and transparent protective film on the surface of the car paint, improve the gloss of the paint, and effectively prevent the erosion of the car paint by ultraviolet rays, acid rain and pollutants.Its waterproof performance makes it difficult for water droplets to attach to the surface of the car paint, which is easy to clean and protects the car paint for a long time.

lubricant
In parts such as car door hinges, sunroof rails, and lock cores, silicone silicone oil as a lubricant can significantly reduce friction and wear and extend the service life of parts.Its excellent lubrication performance and wide temperature application range enable it to maintain a stable lubrication effect under extreme climatic conditions and improve the overall performance of the car.

Sealant
Silicone silicone oil is used for sealing automotive glass, sunroof and joints, which can effectively prevent the penetration of moisture, dust and noise.Its excellent weather resistance and elasticity ensure that the sealing effect can be maintained after long-term use, and improve the comfort and safety of the car.

New energy vehicle field
Battery thermal management: New energy vehicle batteries will generate a lot of heat during the charging and discharging process. With its excellent thermal stability and thermal conductivity, silicone silicone oil can be used as an submerged cooling medium or thermal conductive material for battery packs.It can evenly wrap each battery cell, effectively conduct and disperse heat, prevent the battery from overheating, extend battery life and improve performance.

Motor electronic control system: Silicone silicone oil, as a lubricant and insulating material, can effectively reduce the friction of motor bearings and gears, reduce wear and improve motor efficiency.At the same time, its excellent electrical insulation can also prevent electrical short circuits and other failures of the motor and electronic control system, and ensure the safe driving of the vehicle.
Car charger: The car charger and DC/DC converter will generate heat when working. Silicone silicone oil can be used for heat dissipation and insulation to ensure stable operation in a high temperature environment and improve charging efficiency and system reliability.

3. Future prospects
With the development of the automotive industry in the direction of electrification and intelligence, the application potential of silicone silicone oil in new energy vehicles will be further released.For example, in terms of heat dissipation and sealing of battery packs, the efficient performance of silicone silicone oils will play an important role.At the same time, with the continuous progress of new energy vehicle technology, the requirements for material properties will also continue to increase.With its unique performance advantages, silicone silicone oil is expected to show its unique value in more fields and help the new energy vehicle industry move to a higher level.

In the future, with the continuous development and innovation of materials science, silicone silicone oils are expected to make new breakthroughs in performance and application fields.For example, the introduction of specific functional groups through modification technology can further improve its properties such as lubricity, high temperature resistance and chemical stability to meet more special application needs.At the same time, with the increasingly stringent environmental protection regulations and the continuous improvement of consumer requirements for automotive performance, silicone silicone oil will be more widely used in the field of automotive care, with broad market prospects.
