Selection and Application

The selection of an antistatic agent or additive depends on the specific requirements of the application. Factors to consider include the level of conductivity needed, compatibility with the base material, desired permanence of the antistatic properties, and the economic feasibility of the solution.

For example, antistatic agents for polypropylene are designed to control static electricity build-up, with anti-static masterbatches being particularly useful for controlling electrical discharges in packaging applications (TUBALL). On the other hand, conductive agents such as carbon black, metallised fillers, and carbon fibers can be added to polymers to impart the required level of electrical conductivity. These are often used in applications that demand a higher degree of conductivity, such as conductive plastics.

The application process varies depending on whether the antistatic agent is an internal additive or an external coating. Internal additives are mixed with the polymer before or during the molding process, ensuring that the antistatic properties are inherent to the plastic material. External coatings, however, are applied to the finished product, requiring a separate step in the manufacturing process.

When selecting antistatic solutions, it’s also crucial to consider the end use of the product. For industries that handle sensitive electronics, the level of static protection will be much higher compared to less sensitive applications. Similarly, in healthcare settings, the use of antistatic plastic containers and antistatic plastic bags is paramount to ensure the safety of both patients and equipment.
