Product Introduction:

Electromagnetic shielding film is a type ofelectromagnetic shielding materialAt present, it is mainly used in FPC (flexible printed circuit board) and related components, and is an important raw material for FPC. It has broad application space in the fields of electromagnetic shielding and absorption. Electromagnetic shielding film needs to have the characteristics of high shielding effectiveness, thin thickness, light weight, bending resistance, high peel strength, and low grounding resistance;

The FPC electromagnetic shielding film with polyimide film as the insulation layer includes a PI insulation layer, a metal layer located on the PI insulation layer, an electromagnetic wave shielding coating applied on the metal layer, and a release protective film layer located on the electromagnetic wave shielding coating This utility model should have better weather resistance, flexibility, bending resistance, product flatness, and shielding effect

Product application areas:

Used in insulation, shielding, reflection, heat dissipation and other fields; The material is gentle and can also be used in the fields of electronics and aviation

Mainly used in some special industries and other fields, such as FPC for 5G;

Features and Applications:

1. PI colorless transparent polyimide film has excellent temperature resistance, dissolution resistance, mechanical properties, and excellent transparency, and is widely used in fields such as aerospace, petrochemicals, modern microelectronics, and optoelectronics;

2. Interlayer dielectric materials or flexible printed circuits that can be used for semiconductor devices have special applications in some fields, such as solar cell substrate materials, flexible solar radiation protection materialsFlexible transparent conductive filmBefore the application of substrate materials, alignment film materials for liquid crystal displays, optical waveguide materials in the field of communication, and optical half wave plates for planar optical circuits The scenery is huge;

3. Semiconductor devices, flexible printed circuit boards, liquid crystal displays, solar panels, optical equipment displays, toilet circuit boards, foldable screen displays, and other fields;

4. It can also be used for solar panels and window films; FPC flexible circuit board has a dielectric loss and bendability similar to LCP through PI film modified with fluorine; But the cost is only 70% of LCP;
