How to choose the right PP antistatic agent

This paper will introduce in detail how to choose the right PP antistatic agent from the following three aspects.

PP film is a common plastic film, widely used in food packaging, medical equipment, electronic components, and other industries.

However, the production and use of PP film are easy to generate static electricity, causing many problems, such as dust adsorption, destruction of electronic components, and so on. To solve these problems, we need to choose a suitable PP antistatic agent.

In the process of PP film production and use, static electricity is an inevitable problem. The cause of static electricity is mainly the surface friction of the PP film. After friction, the two objects separated have opposite charges, forming static electricity.

The generation and accumulation of static electricity can lead to dust absorption, interference with electronic devices, and corona. To solve these problems, we need to add antistatic agents to eliminate or reduce static electricity generation.

The preparation method of PP film includes blowing film and casting two kinds of processes, different processes need different antistatic agents. The blowing film process is to heat PP particles to a molten state, through extrusion molding made of film.

In the process of blowing film, the antistatic agent needs to have good dispersion and fluidity and can be evenly distributed in the PP particles to achieve a good antistatic effect. The casting process is the PP particles through the extruder extrusion film, and after stretching and directional processing to form a film.

In the process of casting, the antistatic agent needs to have good thermal stability and tensile properties and can maintain a stable antistatic effect under the action of high temperature and high tensile force.

When selecting the appropriate PP antistatic agent, the following factors need to be considered:

The selection of PP antistatic agent must have a good electrostatic protection effect, can effectively reduce the accumulation of electrostatic charge PP film, and avoid the problem of electrostatic discharge.

When selecting PP antistatic agent, it is necessary to consider its influence on the transparency and gloss of PP film. Generally speaking, the addition of antistatic agents will have a certain degree of influence on the transparency and gloss of the film, so it is necessary to choose the addition of less, less influence on the transparency and gloss of the antistatic agent.

PP film is formed by high-temperature extrusion, so the antistatic agent selected must have good thermal stability and can maintain stability and antistatic effect under high-temperature conditions.

Different types of PP antistatic agents also differ in processing technology. It is necessary to select the appropriate antistatic agent according to the actual processing technology to ensure that it can be compatible with the PP film in the process and evenly dispersed.

When choosing PP antistatic agent, it is also necessary to consider its environmental performance, choose products that meet the requirements of environmental protection, and minimize the impact on the environment.

Combining the above several factors, the selection of a suitable PP antistatic agent can effectively improve the quality and stability of PP film, reduce the negative impact of static electricity, and improve the service life and safety of the film. At the same time, it is also necessary to reasonably control the amount of antistatic agent to avoid excessive influence on the physical properties of the film.
