How do plastics resist static electricity?

Antistatic plastics require that their volume resistivity must be reduced to below 1012Ω·cm, while conductive plastics require that their volume resistivity be less than 106Ω·cm or their conductivity be greater than 2S/cm. There are many different methods for plastic products to resist static electricity, which can be summarized as follows.

1) Use conductive devices to eliminate static electricity during the processing of plastic products.

2) Increasing the air humidity in the processing and use environment of plastic products is conducive to inhibiting the generation of static charges and promoting the leakage of charges.

3) Use blending with structural conductive polymer materials or change the polymer structure through grafting copolymerization to make it carry more polar groups or ionized groups, reduce resistivity, and increase conductivity.

4) Use strong oxidants to oxidize or use corona discharge to treat the surface of plastic products to improve the surface conductivity of the material.

5) Apply a conductive coating or a layer of conductive film on the surface of the product.

6) Add conductive fillers such as graphite, carbon black, metal or metal oxide powder to the plastic, and disperse the conductive fillers into the plastic through mixing to make it a composite conductive plastic.

7) Add antistatic agent to treat the material with antistatic agent to activate its surface and improve the surface conductivity of the material.

These methods have their own characteristics and limitations. In comparison, adding antistatic agent is the simplest and most effective, with low cost, strong practicality and the most common application.

Plastic barrel antistatic uses plastic antistatic agent, which is suitable for antistatic treatment of plastic, does not affect transparency, and the resistance value can reach 10 8-10 11 times, meets environmental protection requirements, FDA, ROHS, REACH, has good compatibility with raw materials, is not affected by temperature and humidity, and has no precipitation. It can effectively prevent the final product from absorbing dust, prevent the product from being contaminated by dust and affecting the appearance and performance of the product, prevent the fire and explosion caused by discharge, and curb the damage caused by static electricity.
