4.Characteristics
4.1.Excellent ESD effect because its interior conductive lattice;
4.2.Able to leaking static electricity rapidly and free of environmental humidity;
4.3.Long time and even Permanent ESD duration(at least 3 years)
5.Usage for PU Conductive
Sponge
5.1. Display devices: displays, monitors ,etc;
5.2. Control circuit: control modules, backlight modules ,etc;
5.3. PU is not only anti-static and buffering ,but also compression resistant ;it is the first material choice applied on LCD, display assembly line and other fixtures ,protecting cushion;
5.4. Mobile phone /3G terminal products especially notebook computers and optoelectronics components circulating Solutions workshop;
5.5. Centralized assembly flow box for notebook computer, every components of a notebook computer can be fitted into the well-designed foam slot. which makes highly assembly efficiency;
5.6. Compared with traditional plastic tray, conductive Polyurethane foam board is not only flexible and buffering ,but also non-traumatic to electric devices and hands ,while traditional hollow board is very easy to scratch electronic devices and hand in the process of use, The most important thing is that Polyurethane foam's life is as several times longer as hollow boards;
5.7. Packaging solutions for the electronic products prone to static electricity in the process of transportation;
5.8. Designed in accordance with the shape of electronic products , Polyurethane foam is an extremely ideal packaging material to avoid electrostatic, shock and shaking for many electronic products i the process of transportation, especially in overseas shipment;
5.9. Polyurethane foam has been widely used as fixtures and protecting cushion for many electronic products because of its excellent secondary processing anti-static effect combined with its good compression resistance, wear resistance performance.
