Problems solved by technology

However, many rubber and plastic materials usually have electrical insulation, such as polyethylene (PE), polypropylene (PP), the surface resistance is generally 10 16 Ω, soft polyvinyl chloride (PVC) is 10 14 Ω, so once charged by friction, it is not easy to eliminate, resulting in static electricity
Due to electrostatic attraction, rubber and plastic products will absorb dust and other debris in the air, which will affect the appearance of the product
[0003] In the prior art, the additive antistatic agent is an important auxiliary agent for antistatic rubber and plastic materials, and the annual demand is constantly increasing, but its compatibility with polymer materials, volatility, and durability are still lacking. has a big deficiency
