Introduction of Heatsink Adhesives
With the miniaturization and high power of electronic products, more and more heat is generated, so we have the need to quickly disperse the heat out, and then add an aluminum alloy heatsink to heating element. If there is a gap between the heating element and heat sink hinder the heat transmission, so we have to fill the gap with thermally conductive material to increase the cooling effect, and at the same time, we need to fix the heatsink compound on the heating element. Heatsink adhesive just has both functions. It has thermal conductivity and adhesive fixing properties. The fins binder is mixed from room temperature with curable silicone rubber and a thermal insulation material. The silicone rubber has excellent insulation, heat resistance, aging resistance and bonding properties. Thermal oxide powder has high thermal conductivity, but without conductive property.  Heatsink Adhesive Applications
Heat Sink Paste is used for the completion of heat transformation between the heating parts and the cooling parts, and it can increase the heat transfer area, and also play the damping, insulation, sealing and other effects, to meet the social device miniaturization slim fanless design requirements, and it uses new materials. It is a very good industrial product and the thermally conductive material with very convenient use. When tear the protective film, it is flexible, and it can work to complete the heat transformation between heat-generating part and cooling part. Heatsink adhesive products are widely used: the built-in power modules, the backlight module, LED lighting, switches, hubs, network cards, modems, transmission equipment, semiconductor lighting equipment, test / control of medical equipment, power supply module, close contact for electronic products, electronic equipment, heating power devices (integrated circuits, power transistor, SCR, transformers, etc.) and cooling facilities (heat sink, aluminum housing, etc.), to achieve better thermal effect.
Adhesives Classification
There are many different types of adhesives, usually it can be classified as follows: according to sources of material, it can be divided into: natural adhesives, artificial binders, water soluble adhesives, hot melt adhesives, emulsion adhesives and the solvent-based adhesives. The natural binder is substance derived from the nature. Biological adhesives including starch, protein, dextrin, gelatin, shellac, hide glue, rosin; and also including asphalt and other mineral binders. Artificial adhesive is the organic binder, including an inorganic binder such as water-glass, and a synthetic resin, synthetic rubber or the artificial-like substance. The water soluble binder use the binder with water as the solvent, mainly starch, dextrin, polyvinyl alcohol, carboxymethyl cellulose, etc. Hot-melt type adhesive is by heating the adhesive, and after melting, it can be used as a solid binder.
