What is thermal conductive double-sided tape?

Thermal conductive double-sided adhesive is made of acrylic polymer mixed with thermal conductive ceramic powder, Double Sided Tapecoated on both sides of glass fiber cloth and compounded with organic silica gel adhesive. It has the characteristics of high thermal conductivity and insulation, and has certain softness, compressibility, adhesion and strong viscosity. It can withstand a wide temperature range.

Process principle of heat conductive double-sided adhesive

Consistent with the working principle of thermal conductive silica gel, the thermal conductive double-sided adhesive is also filled on the uneven surface to make the heat sink and heat source closely fit together, so that the original air heat conduction becomes the current thermal conductive double-sided adhesive.

Heat conductive double-sided tape is widely used in bonding heat sink, heat dissipation module, Double Sided Tape CPU microprocessor heat dissipation, LED lamp heat dissipation, filling the gap between PCB, metal components and casing, and conducting heat outside the uneven surface. It can be used even in a confined space without changing any components, It fully reflects the thermal conductivity of this heat conducting material and the self-adhesive and convenient use characteristics of pressure-sensitive tape.

The thermal conductive double-sided adhesive has the advantages of simple and convenient operation and high work efficiency. When in use, just tear off the release paper (stripping paper) on the surface of the thermal conductive double-sided adhesive, and then stick the adhesive surface on the device surface and gently press it to bond immediately. So that there is no need for mechanical fixation and liquid adhesive curing between electronic components and radiators.

Heat conductive double-sided adhesive can be divided into with or without substrate according to different materials. It can also be divided according to the composition of the substrate, glue composition, etc.

The main material components are divided as follows:

1. With or without base material;

2. No base material, cotton paper, pet, foam, non-woven fabric, cloth;

3. Waterborne acrylate, oily acrylate, solvent rubber, hot melt adhesive and silicone.

Characteristics of heat conductive double-sided adhesive

1. High thermal conductivity. Super heat transfer, heat conduction and heat dissipation. The thermal conductivity of the thermal conductive double-sided adhesive is 0.8-1.0w / m.k, which solves the problem that the scattered thermal conductive paste is difficult to operate, the coating is uneven, and the adhesive overflow causes defective products.

2. anti aging. The working environment of thermal conductive double-sided adhesive is generally in high heat, high temperature, large temperature difference and rich in ultraviolet light. Therefore, the thermal conductive tape must be resistant to low temperature (- below 20 ℃), high temperature (+ above 120 ℃) and perennial ultraviolet radiation. Working in various complex environments will not reduce the thermal conductivity.

3. Replace rivets and other mechanical operations. When the traditional LED assembly is Double Sided Tape considered by the cost of human resources, reducing processes and improving products have become the only choice for the LED industry. More and more led enterprises are thinking about using thermal conductive double-sided tape to replace traditional mechanical operations such as rivets and screws, which not only plays a fixed function and role, but also gives full play to the role and function of thermal conductive double-sided tape.

4. Shock absorption function. Heat conductive double-sided adhesive is foamed by fully injecting air into acrylic (acrylic) base material, with shockproof and shock absorption functions.
