Plastics are polymer materials, and the surface resistance and volume resistance are greater than the 12th power of 10. Therefore, it gives good insulation properties to plastic materials. It is precisely for this reason that it is very easy to generate static electricity, because plastics and their products are very possible in the production, handling, contact, separation, friction, collision and intervention of electromagnetic induction, and even it is absolutely impossible to avoid these occasions, which brings the generation factors of static electricity. The effective control method is to add some hygroscopic and harmless (auxiliary) materials to reduce the surface resistance of plastics. This is the antistatic agent of plastics. The type of antistatic agent selected according to different plastic varieties is used to achieve the antistatic performance.
