Which is better between thermal conductive silicone rubber heating mat and thermal conductive grease?

With the advancement of technology， many old products are slowly being replaced by new ones. However, in the market of thermally conductive materials, the two products of thermally conductive silicone rubber heating mat and thermally conductive grease have maintained a steady development. This also makes many people entangled, unable to distinguish the two very well. So, Which is better between thermal conductive silicone rubber heating mat and thermal conductive grease?

Thermal effect

Both of them are thermally conductive materials. If you want to distinguish from the essence, you need to start from the thermal effect. Although, most people know that just look at the thermal conductivity, the thermal conductive silicone rubber heating mat will be higher.  In fact, looking at the thermal conductivity, it also depends on the thermal resistance. Thermal resistance is inversely proportional to thermal conductivity. In order to better distinguish, here is a comparison between two materials with the same thermal conductivity, so that only the thermal resistance is needed. By comparison, thermal grease will be better.

Anti-aging performance

The aging performance is related to the shape of the material, and at the same time, the aging performance determines the length of the service life. Then, it is okay to use the aging performance to judge which is better between the thermal conductive silicone rubber heating mat and the thermal conductive silicone grease. The thermal conductive silicone rubber heating mat is piece by piece, then the internal silicone oil will be difficult to volatilize, and it has strong aging resistance. Let’s look at thermal grease, which is generally liquid paste and not very stable. Coupled with the use of thermally conductive materials to help dissipate heat, it will be in a high temperature environment for a long time. High temperature will affect the performance of the paste, and the precipitated material is normal. The natural result is that the thermal conductive silicone rubber heating mat wins.

Use range

We all know that many products now require thermally conductive materials to aid heat dissipation, and they are used in washing machines, microwave ovens, and air conditioners at home. It can be seen that thermally conductive materials with a wide range of applications are more popular. Among them, the thermal conductive silicone rubber heating mat is a sheet-like object, which can be cut at any time according to the size of the required part. With good softness and thinner thickness, it can be used in many products. Thermally conductive silicone grease has some limitations. If it is applied thick or thin, it will affect heat dissipation.

Cost

If the price can influence people to judge which is the best result of thermal conductive silicone rubber heating mat and thermal conductive silicone grease, then we can only analyze from the cost. Although the thermal conductive silicone rubber heating mat uses organic silicon materials, it is to reduce costs. But the cost of smear-type thermal grease is lower. Besides, the process involved in cost is generally more complicated with thermally conductive silicone rubber heating mats. It can only be said that thermal grease is more dominant in this link.

It is difficult to judge which of these two is better. These comparisons can only show that the pros and cons are equally divided. Of course, the analysis content involved can help you choose the thermal conductivity material that suits your product or equipment. After all, the fit is the best, and the real win or loss is not very important.
