What are the reasons for the widespread use of thermally conductive silicone sheets?

High thermal conductivity silicone gasket is a new product derived from the progress in the heat dissipation adhesive market. It is mainly a kind of thermal conductivity medium material synthesized by a special process with silica gel as the base material and various auxiliary materials such as metal oxides. , Used to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat sink. It is specially produced for the design scheme of using the gap to transfer heat, and completes the heat transfer between the heating part and the heat dissipation part. It is an excellent thermally conductive filling material.

The things made of silica gel are still very popular with the public. After all, they are relatively environmentally friendly. They are also very convenient to use and the price is particularly suitable. Therefore, thermally conductive silicone sheets are widely used in various industries; then, thermally conductive silicone sheets are widely used What is the reason? Today, the editor will introduce the application principle of high thermal conductivity silicone gasket.

Excellent thermal conductivity

You should know that the thermal conductive silicone sheet is relatively soft, and can be used as a pad in many electronic precision mechanical product heat dissipation modules. It is also relatively soft and convenient to use. In addition, because silica gel is an important raw material, silica gel has good thermal conductivity and strong elongation performance, so it will gradually expand after being applied to the gaps of some small parts, and the gaps will be continuously filled, and naturally it will not be lost. More heat, so that the heat can be well conducted.

Good insulation properties

Since it is used in electronic precision mechanical products, the performance requirements for the materials used are still relatively strict, and insulation is of course essential. Many electronic products need to use some thermally conductive gaskets. Only in this way can they be mechanically fixed well, but at the same time, the insulation properties of the thermally conductive gaskets must be considered, so that they will not appear during use. The leakage of electricity is really dangerous otherwise. At this time, silica gel, which has its own insulating properties, can show its talents. Because of its insulating properties, it is processed into a thermally conductive silicone sheet and can be directly applied to the connection between the heat source of the product and the heat sink.

Low price

Not all products that sound tall are expensive. Some things just look novel, but the price is still acceptable to the public. Silica gel is a living example. The cost of thermally conductive silicone sheets made from it is still very low. The extremely thin sheet shape is very material saving, so the input cost is greatly reduced, and its price will gradually decrease. Many people value this advantage and use it in the product cooling solution!

Environmental safety

Nowadays, the general public still pays great attention to safety and environmental protection. Most of the material of the thermal conductive silicone film is silica gel. In addition to adding some environmentally friendly glue, the thermal conductive silicone film does not need too many other ingredients. Therefore, it is still very environmentally friendly and safe. of.

It is worth mentioning that the main purpose of selecting high thermal conductivity silicone gasket is to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat sink. The high thermal conductivity silicone gasket can also fill the gap of the contact surface and squeeze the air out of the contact surface. Air is a poor conductor of heat, which will seriously hinder the transfer of heat between the contact surfaces; with the supplement of the thermally conductive gasket, the temperature response can reach the smallest possible temperature difference, which can make the contact surfaces better and fully contact, and Make face-to-face contact.

With the development of technology, thermally conductive silicone gaskets have been widely used in communication equipment, computers, switching power supplies, flat-screen TVs, mobile equipment, video equipment, network products, medical equipment, household appliances, PC servers, workstations, optical drives, COMBO, Base stations and other fields. More industry applications in the future are waiting for thermal silica film manufacturers to explore and discover.
