Basic Process:
The said product is a close-cell, conductive soft foam. It is produced by compounding the EVA resin with conductive fillers& blowing agents to extrude certain sheets, then molding and foaming. Sheet being molded, the conductive filler forms conductive channel/ network internally, so as to achieve the purpose of static discharge.

Characteristics:
1.Excellent and permanent ESD effect, free of environmental humidity;
2.Superior buffering and cushioning performance: independent and meticulous closed cell;
3.Excellent conductive effect: resistivity value 103—109 Ω/sq
4.High temperature resistance: EVA resists a maximum temperature of 80°C
5.Chemical corrosion-resistant: resistant to organic solvents, acids, alkalis, etc;
6.Non-chemical corrosion: free chemical corrosion to the electronic devices and the packing materials;
7.Heat insulation, sound insulation, abrasion resistance; hard to lose and consume;
8.Satisfactory performance of secondary processing, easy to shape.
Use and applications:
1.workshop assembly, flow
2.Motherboards, circuit board workshop circulation, packaging solutions for the electronic products prone to static electricity in the process of transportation
3.Advantage:
(1)EVA is not only anti-static and buffering, but also compression resistant, it is the first material choiceapplied on LCD display assembly line and other fixtures, protecting cushion;
(2)EVA 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;
(3)Compared with traditional plastic tray, conductive EVA foam board is not only flexible and buffering, but also non-traumatic to electric devices and hands, while traditional plastic tray is very easy to scratch electronic devices and hand in the process of use, The most important thing is that EVA foam’s life is as several times longer as plastic tray.
