Difference between thermal conductive gel and thermal conductive silicone grease

Thermal conductive gelThermal conductive silicone grease is a rising star in the field of thermal conductive materials in recent years, and it is an elder member of the thermal interface material family. The two types of thermal conductive interface materials are both paste like. Many customers estimate that the difference between thermal conductive gel and thermal conductive silicone grease has always been unclear. Some people still mistakenly think that thermal conductive gel is thermal conductive silicone grease, just a different name. Today, I will discuss the difference between thermal conductive gel and thermal conductive silicone grease.

The construction methods of thermal conductive gel and thermal conductive silicone grease are different

Thermal conductive gel is a kind of thermal conductive material with ultra-high adhesion, which is made of a variety of thermal conductive powders and thermal conductive silica gel after mixing and fully maturing. The entire production process must be completed in a vacuum state, so the thermal conductive gel is in a vacuum state without any air before use. The packaging of thermal conductive gel is also needle cylinder or bottle packaging, which can be dispensed directly by the full-automatic dispenser during construction, so as to achieve high efficiency of automatic production. The thermal conductive silicone grease is different from the thermal conductive gel in terms of both the formula and the production process of the thermal conductive silicone grease itself. The packaging method of the thermal conductive silicone grease is also simple canned or barreled. In recent years, many manufacturers have also used the needle tube packaging method to facilitate operation. The conventional construction method is screen printing, but some customers use it more conveniently by simply applying and scraping it evenly. But such a simple construction method also requires manual operation. To put it simply, the thermal conductive gel can be constructed using the fully automatic dispensing process, while the thermal conductive silicone grease is currently mostly constructed manually.

The working life of thermal conductive gel is different from that of thermal conductive silicone grease

Heat conducting gel is a kind of heat conducting material that is permanently dry and can be infinitely compressed. For example, the thermal conductive gel that spans the electronics can guarantee the service life of customers more than 10 years. Some people in the industry refer to thermal conductive gel as liquid thermal conductive silica gel sheet. However, the production process requirements for thermal conductive silicone grease are not high, and the manufacturers are uneven. Thermal conductive silicone grease with slightly lower quality has a very short service life. Most thermal conductive silicone grease begins to dry up and turn into powder after six months of use, and can be completely turned into powder in no more than two years. With just a pinch, it turns into dust, and the thermal conductive silicone grease loses its thermal conductivity, which means its lifespan is over. This is also a fatal development and promotion bottleneck for the development of thermal conductive silicone grease, which has been roast most.

There are many differences between thermal conductive gel and thermal conductive silicone grease. For example, product thermal resistance, thickness, etc. Therefore, through the above detailed explanation, it should be clear that thermal conductive gel is not thermal conductive silicone grease, and there is a huge gap between the two in terms of use mode and performance characteristics. Therefore, customers can choose to use thermal conductive gel or thermal conductive silicone grease according to their own product characteristics and product structure requirements.
