Problems solved by technology

[0002] Polymer materials have good corrosion resistance, easy processing, and can meet the requirements of various special purposes. They have been widely used in many fields, but they are all non-conductive insulators, and there will be static electricity accumulation, electromagnetic interference, etc. during use, not only It will cause adverse effects during processing, and may also cause some accidents during use.
Packaging materials made of polymer materials often have accidents during the production process due to static electricity that cannot be eliminated, and may affect the quality of the packaged items. These problems not only affect the convenience of use of the materials, but also hinder the use of polymer materials. development, it is therefore necessary to address the above
The electrostatic problem can be solved well by adding conductive fillers in polymer materials. Metal silver has excellent electrical conductivity, but it is more expensive and can only be used in some special occasions. Copper has better electrical conductivity, but copper powder The dispersion in the matrix material determines whether it can play a good shielding effect
