Technical Field
The utility model relates to the field of Mylar films, in particular to an anti-electromagnetic interference Mylar film.
Background
The Mylar polyester film is a film which is formed by heating dimethyl terephthalate and ethylene glycol under the assistance of related catalysts, performing ester exchange and vacuum polycondensation, and performing biaxial stretching. The Mylar film has various color classifications such as milky white, black, natural color, transparent color and the like. Mylar is divided into a plurality of materials, such as PET Mylar, PVC Mylar, PC Mylar, fireproof Mylar and the like. Can be used as the insulating material of motor, capacitor, coil and cable. The conventional mylar film is mostly used in electronic elements to play a role in insulation protection, but the conventional mylar film has a single function, cannot play a role in shielding electromagnetic waves generated between the electronic elements to form mutual interference in the electronic elements, and cannot achieve comprehensive shielding and insulation.
