An efficient electromagnetic shielding clutter absorption material with high thermal conductivity and soft, self-adhesive absorbing properties

Time：2021-12-14Number：1259

Electromagnetic shielding, noise absorption, high thermal conductivity, soft and adhesive absorbing material wholesale

Product Introduction

Electromagnetic wave absorberDivided by conductive loss, dielectric loss, magnetic loss, etc., it can be divided into conductive absorber materials, dielectric absorber materials, andMagnetic absorber materialMainly based on dielectric loss as the loss mechanism, under the action of an external alternating electric field, the electrons inside the material fibers vibrate, converting electromagnetic energy into thermal energy and consuming it.

Characteristics and advantages

Electromagnetic shielding, clutter absorption, high thermal conductivity;

Soft, self-adhesive, low thermal resistance under low fastening pressure;

Application design under low adhesion, low hardness, and low pressure;

UL94-V0 is flame retardant and can be cut;

Has good thermal conductivity, high compression ratio, insulation, and is easy to operate.

application area

Between semiconductor and heat sink; Thermal conduction between power devices and casings or other heat sinks; Gap filling, thermal conductivity, and insulation between the power amplifier tube and the radiator; Heat dissipation applications that require stress or vibration absorption, shock resistance, insulation, and thermal conductivity; Applied to the communication industry, laptops, control motherboards LCD-TV、 High power supply, LED lighting, etc.
