Plastic conductive carbon black, which power has the best antistatic effect?

How much plastic antistatic carbon black needs to be added?

The concept of plastic anti-static:
When the surface resistance of plastics and products is greater than the 10th power, it is very easy to generate static electricity; it has a certain antistatic performance between the 8th and 10th powers; it has good antistatic performance between the 6th and 8th powers; It has the best anti-static performance between the 6th power; when it reaches the 4th power, it has considerable conductivity and belongs to the conductive semiconductor material.

Prevention and treatment of static electricity in plastics: antistatic carbon black

1. Add some moisture-absorbing and harmless (auxiliary) materials to plastics to reduce their surface resistance. This is the antistatic agent for plastics. The type of antistatic agent selected according to the variety of plastics is used; whether it is an ionic type The non-ionic type belongs to the hygroscopic antistatic agent. After adding these additives, this kind of material absorbs moisture in the air and reduces the surface resistance to achieve antistatic performance.

2. Directly use conductive plastics to process its products, which is the origin of conductive plastics (resins). From the current domestic market, most conductive plastics are still black-colored additive conductive carbon black plastics; light-colored The variety of conductive plastics is still in the process of development.

Antistatic agents - selection of conductive plastics
Antistatic agents are mainly produced in Zhejiang, Shanghai, Beijing and other places. According to the plastic types, they are divided into PVC, PP, PE, ABS, HIPS and other types. The value is: 10 to the 8-10th power, especially in areas with high humidity, the value is obviously smaller.

Made of highly conductive carbon black, its varieties include PC, PET, PP, PE, ABS, HIPS, PVC and various plastic alloys, but most of them are black and the price is 16-30 yuan/kg. The main producing areas are Hebei, The emergence of anti-static plastics in Beijing and other places plays a very important role in promoting and developing plastic products, and also guarantees the demand for anti-static products. Especially the packaging of electronic products and plastic products that require anti-static applications .From the analysis of the current situation, the increase in demand has a good momentum of development.
The effect of foreign imports is better than domestic ones, even if used in relatively dry areas, it can reach the 8th power. Due to the mechanism of action of this type of antistatic agent, the antistatic performance can no longer be improved. Antistatic masterbatch is for the use of most plastic raw materials All are granular, but the price is higher than the domestic market.
