Which thermal interface materials can be back glued? What does it do?

Thermal interface material adhesive generally refers to a layer of double-sided tape on the surface of the original material, one side is attached to the thermally conductive material, and the other side is leaking out. During use, tearing off a layer of protective film on the surface can play a fixed role. . Of course, there are also double-sided adhesive, the method is the same as single-sided. Some thermally conductive materials have some stickiness themselves, so they can be used without adhesive. This adhesive is made according to customer needs.

The thermally conductive interface materials that can be backed include: thermally conductive silicone sheet, thermally conductive silicone cloth, etc.

Thermal silicone pad

The thermally conductive silicone sheet is specially produced for the design scheme of using the gap to transfer heat. It can fill the gap and complete the heat transfer between the heat-generating part and the heat-dissipating part. Thinning design requirements, with manufacturability and applicability, and a wide range of thicknesses, a good thermal conductive filling material.

The thermally conductive silicone sheet has natural viscosity, and the purpose of the adhesive is for better viscosity. At the same time, the thermally conductive silicone sheet with adhesive backing will increase the thermal resistance and reduce its thermal conductivity. Therefore, when you buy thermally conductive silicone sheets, you should decide whether to back glue according to your own needs.

Thermal insulation sheet

Thermal insulation sheet is a silicone polymer elastomer reinforced with glass fiber as a base material, also known as thermally conductive silicone cloth, tear-resistant silicone cloth, this silicone cloth can effectively reduce the gap between electronic components and radiators. High thermal resistance and electrical insulation, high dielectric strength, good thermal conductivity, high chemical resistance, can withstand high voltage and short circuit caused by metal puncture, is a substitute for traditional mica and silicone grease An excellent thermal insulation material.

The thermal conductive silicone cloth itself has no adhesive backing, that is, it is not sticky. The advantages of the thermal conductive silicone cloth are strong breakdown resistance, wear resistance, tear resistance, puncture resistance, good high-voltage insulation performance, and thin thickness. It can also be glued back.

The above two thermal interface materials are produced in large quantities by Nuofeng NFION Thermal Materials Factory, which are also hot-selling products, and are widely used. They can be customized according to customer needs with adhesive, die-cutting and different specifications.
