Omnidirectional conductive foam is a three-dimensional mesh structure functional material that integrates conductivity and electromagnetic shielding functions. It is mainly composed of foam and conductive cloth wrapped around the foam.
Composition and Production
-
Main materials: The main material of the all-round conductive foam is polyethylene or modified polyethylene, and conductive fillers and anti-static agents are added.
-
Production process: Firstly, extrusion molding is carried out, followed by radiation crosslinking and high-temperature foaming. After foaming is completed, process a tape wrapped in conductive cloth around the sponge to provide shielding and conductivity to the electronic shielding material.
Characteristics and advantages
-
Low cost: Due to relatively low production costs, its selling price is also very cheap.
-
Good three-dimensional shielding effect: As an upgraded product of conductive foam, all-round conductive foam has a three-dimensional shielding effect, and the shielding effect is stronger than conductive foam.
-
Soft and easy to process: The main material is sponge, which is soft and easy to process or use for packaging, suitable for various places and environments.
-
Permanent conductivity: The conductive cloth used is vacuum electroplated metal material, which has good permanent conductivity.
-
Strong bending durability: It has good bending durability and is very suitable for situations with limited capacity and closing pressure.
-
Good shock absorption effect: The sponge is produced by foaming technology of polymer polyurethane composite material, with uniform foaming pore size, softness, elasticity and strong corrosion resistance, and has good shock absorption effect.
-
Excellent anti-corrosion performance: The sponge surface is electroplated to ensure good conductivity, and the outermost nickel layer also increases the material's anti-corrosion performance.
application area
Omnidirectional conductive foam is widely used in various electronic and electrical equipment due to its excellent performance, for EMI (electromagnetic interference) and EMS (electromagnetic tolerance) prevention and control. Specific application areas include PDP TVs, LCD displays, LCD TVs, mobile phones, laptops, MP3 players, communication cabinets, medical instruments and other electronic products, as well as military and aerospace fields.
Omnidirectional conductive foam is a high-performance, low-cost, and widely used conductive electronic shielding material. With the continuous development and popularization of electronic products, their market demand will also continue to grow.
