Vinyl silicone oil is a linear or branched polydimethylsiloxane composed mainly of silicon-oxygen bonds (-Si-O-) and vinyl groups (-CH=CH2) and other organic groups attached to the silicon atoms. This structure gives vinyl silicone oil good thermal stability, allowing it to maintain its performance at high temperatures. In addition, vinyl silicone oil has a low surface tension and is easy to compatibilize with other materials, making it widely used in many fields.

Vinyl silicone oil is an excellent heat transfer medium due to its superior thermal conductivity. Its thermal conductivity is mainly attributed to the silicon-oxygen bonds in its molecular structure, which effectively transfer heat. Therefore, vinyl silicone oil is widely used in heat transfer products, especially in the electronics industry.

Vinyl Silicone Oil as a Heat Transfer Medium in Heat Sinks

Application:

Vinyl silicone oil is widely used as a heat transfer medium in heat sinks due to its excellent thermal stability and good thermal conductivity. In electronic devices, when core components such as chips and processors operate, they generate a significant amount of heat. To ensure that these devices operate at normal working temperatures and avoid overheating that can lead to performance degradation or damage, heat sinks are used to effectively dissipate this heat. Vinyl silicone oil plays a crucial role here, as it can form good thermal contact between the heat sink and the heat-generating components, improving heat transfer efficiency.

Electronic Device Heat Dissipation

Vinyl silicone oil can be used as a heat transfer medium in electronic devices to conduct and dissipate the heat generated by electronic components, thereby protecting the performance and lifespan of the devices.

LED Heat Dissipation

LED light sources generate heat during operation. Vinyl silicone oil can be used as a heat transfer medium to dissipate this heat, thereby improving the performance and lifespan of LEDs.

Solar Panel Heat Dissipation

Solar panels generate heat when exposed to sunlight. Vinyl silicone oil can be used as a heat transfer medium to dissipate this heat, thereby improving the efficiency of solar panels.

Electronic Encapsulation Materials

Vinyl silicone oil can be used as an electronic encapsulation material to seal and dissipate heat from electronic components, ensuring their stability and reliability. It is widely used in high thermal conductivity silicone gels and thermal pads.

Properties:

Compared to traditional heat transfer media, vinyl silicone oil has higher thermal stability and lower volatility. This means it can maintain stable performance under high-temperature environments and its thermal conductivity won't decline due to volatilization. Additionally, vinyl silicone oil has good chemical stability and is not prone to reactions with other materials in electronic devices.

Manufacturing Thermal Grease

Applications:

Vinyl silicone oil plays a crucial role in the manufacturing of thermal grease. Thermal grease is a heat-conductive material used to fill the tiny gaps between high-performance chips like CPUs and GPUs and their heat sinks. These gaps, if left unfilled, impede heat transfer and hinder heat dissipation. Thermal grease, with its vinyl silicone oil component, forms an efficient heat conduction path, facilitating rapid heat transfer from the chip to the heat sink.

Properties:

Thermal grease made from vinyl silicone oil exhibits exceptional thermal conductivity, excellent stability, and a long lifespan. Additionally, it possesses low viscosity and good lubricity, enabling the formation of a uniform heat-conducting layer between the chip and the heat sink, ensuring even heat distribution and effective transfer.
