General application, rakish feature good with processability.But plastics are typically all what is insulated, development and section with society
The progress of skill, the application range of plastics is more and more wider, and the requirement of people is also higher and higher, and insulating properties can cause plastic products table
The electrostatic charge that area tires out can not be released, and then form electrostatic pressure, easily adsorbed dirts, the electrostatic potentials such as dust and reached certain
After degree, static discharge can be generated（ESD）With shock phenomenon.Especially in electronics industry, various precision instruments and precise electronic
Element can be damaged or even scrapped due to electrostatic breakdown, in addition, in the industrial and mining enterprises of some contact inflammable and explosive substances, electrostatic is put
If electricity cannot be protected effectively, more serious consequence can be generated, it may be with regard to entail dangers to field worker once there is accident
Life, and cause great economic loss.On the other hand, with the development of modern electronics industry, Electromagnetic Interference（EMI）With penetrate
