Abstract

The invention provides an FFC high-frequency transmission hot melt adhesive film, which comprises a polyester film and a hot melt adhesive layer on the polyester film. The hot melt adhesive layer comprises the following components by weight: 30-40 parts of polypropylene; 25-35 parts of an ethylene vinyl acetate copolymer; 18-23 parts of a brominated flame retardant; 8-15 parts of an antimony-basedflame retardant; 20-30 parts of fumed silica; and 0.1-0.3 parts of a coupling agent. According to the FFC high-frequency transmission hot melt adhesive film provided by the invention, the signal interference and attenuation of the insulating layer to conductor transmission can be reduced, the conductor signal transmission speed is improved, and the requirement on high-speed transmission is met.

Description

technical field [0001] The invention belongs to the field of adhesives for cable insulating materials, in particular to an FFC high-frequency transmission hot-melt adhesive film. Background technique [0002] With the improvement of people's living standards, the requirements for various life and entertainment equipment have also increased accordingly. As a common device for daily viewing and entertainment, high-definition TVs have higher and higher requirements for image quality and definition (resolution). Ultra-high-definition resolution will bring us an immersive feeling when watching images. Watch and enjoy. For example, 8K TVs have 8K ultra-high-definition resolution (7680×4320), which is 16 times larger than the resolution of 1920×1080, and the definition will be 16 times that of the Blu-ray version. In order to meet the development requirements of 4k and 8k high-definition televisions, the internal signal transmission of televisions needs to be gradually strengthen...
