Plastic is a poor conductor of electricity, which means that when it comes into contact with another surface, it can cause a buildup of static electricity. This can result in sparks, shocks, and the attraction of dust and other particles. To dissipate static electricity from plastic, you can increase humidity or moisture, as water improves conductivity. Anti-static sprays or foams can also be used to coat the plastic with a thin layer of conductive material, preventing static buildup. Alternatively, you can use antistatic brushes or ionizing rods to remove static charges.

What You'll Learn
Use water or moisture to increase conductivity
Water is a good conductor, so increasing the humidity or adding a slight amount of moisture to plastic will make it more conductive and quickly dissipate static electricity. This is because water provides an exit route for electrons to move through, reducing the surface charge.
One way to do this is to spray a diluted solution of water and dishwashing soap onto the plastic. This will form a film that controls static buildup. This method was used historically in the aerospace and missile industries.
Alternatively, you can use anti-static sprays or foams, which are widely available online and in drugstores. These sprays coat objects with a thin layer of conductive "skin" that prevents static cling. However, it is important to use caution when handling such chemicals and to read all warning labels and instructions before use.
Another method is to use a grounded whiskered pickup to touch the surface of the plastic. This should cover as large an area as possible. Laser printers, for example, use this method to discharge static electricity from moving paper sheets.
Finally, simply increasing the humidity in the environment can help to dissipate static electricity from plastic. This is because higher humidity reduces the speed of separation between surfaces, which in turn reduces the buildup of static charge.

Use anti-static sprays or foams
Anti-static sprays or foams can be used to dissipate static electricity from plastic. These products are designed to eliminate static electricity and prevent the buildup of static charges. They can be applied to plastic surfaces to make them conductive, allowing any existing static charge to dissipate and preventing new charges from forming.
One such product is the ACL Staticide 8670 Anti-Static Plastic & Glass Cleaner Spray. It is a foaming spray that effectively cleans, polishes, and neutralizes charges. It is safe to use on plastics, glass, and stainless steel and is ideal for optical surfaces as it does not streak, smear, scratch, or abrade.
Another option is the MG Chemicals 826 Static Off Antistatic Plastic Cleaner, which comes in a 450g aerosol can. It is designed to add anti-static protection to plastic partitions and has been found effective on LP records. However, some users have noted that it requires weekly touch-ups during the winter months and that the effects may not last long.
There are also anti-static sprays available for specific types of plastic, such as plexiglass. These sprays can be purchased from online retailers like Amazon.com. When using anti-static sprays or foams, it is important to follow the manufacturer's instructions and take any necessary precautions, such as avoiding spraying near metal objects to prevent rusting.
It is worth noting that anti-static sprays and foams are not the only methods to dissipate static electricity from plastic. Other techniques include increasing humidity, using grounded whiskered pickups, anti-cling sheets, or ion pumps. Additionally, static charges can be removed using tools like StaticElastic and Ion360 Rods, which are placed near the plastic surfaces to eliminate static charges and prevent dust attraction and shocks.

Use brushes to remove static electricity
Plastic is a poor conductor of electricity, which means that it tends to hold onto electrons, leading to a buildup of static charge. This makes plastic useful in certain applications, but it can also attract dust and other particles, causing various issues.
One way to remove static electricity from plastic is by using brushes designed for this purpose. These brushes can help to remove static charge and prevent dust and lint pickup. Traditionally, antistatic brushes used a polonium strip with an attached brush. However, due to safety concerns, alternative options should be considered.
One alternative is to use a diluted solution of water and dishwashing soap. By spraying this solution onto the plastic surface and not wiping it off, you can create a film that helps control static buildup. This method is similar to those used in aerospace and missile plants in the past.
Another option is to use anti-static brushes specifically designed for the photo business. These brushes can help remove dust and lint pickup on negatives before printing. Additionally, vinyl lovers often use a spray that removes static charge without leaving any residue, which can be found in HiFi stores.
It is important to note that the effectiveness of brushes in removing static electricity may vary depending on the specific type of plastic and the level of static charge. In some cases, combining brushing with other methods, such as humidity control or grounding techniques, may be more effective in dissipating static electricity from plastic surfaces.

Increase humidity to reduce static charge
Plastic is a poor conductor of electricity and is prone to static electricity. This occurs when two or more surfaces come into contact and are separated, resulting in a transfer of negative electrons from one surface to another. The level of charge depends on several factors, including humidity.
Low humidity increases the risk of static electricity build-up. This is because moisture in the air is a natural conductor, providing a pathway for excess charges to be released into the air harmlessly. When the humidity is low, the air is dry, and a non-conductor, so the charges have nowhere to go.
To reduce the risk of static electricity, the relative humidity should be kept above 40%. Ideally, the humidity should be between 40% and 60%. At this level, the moisture in the air is high enough to allow excess charges to be released, and the moisture will also settle on surfaces, forming a conductive layer that provides further protection.
There are several ways to increase humidity to reduce static electricity. One way is to use an evaporative humidifier, which can help to maintain consistent climate control. Another way is to use a high-pressure air humidifying system, which is a cost-effective method for improving productivity and reducing the risk of electrostatic discharge (ESD).

Use grounded whiskers to cover the plastic surface
Plastic is a poor conductor of electricity, which is why static electricity can build up on its surface. This occurs when two or more surfaces come into contact and are separated, causing a transfer of negative electrons from one surface to another. The level of charge depends on the material's properties, humidity, temperature, pressure, and speed of separation.
One way to dissipate static electricity from plastic is to use grounded whiskers to cover the plastic surface. This method is often employed in products like laser printers to discharge static electricity from moving paper sheets before they exit the printer. The whiskers should be grounded and cover as much surface area as possible to effectively dissipate the static charge. This technique can help to prevent static shocks, contamination from dust and particles, and other issues caused by static electricity.
Grounded whiskers can be an effective solution for plastic with a high static charge, such as freshly molded plastic parts or containers. By placing the whiskers in contact with the plastic surface and ensuring they are grounded, the static electricity can be safely discharged. This method is especially useful when handling multiple plastic items, as it can prevent the static charge from building up and causing issues during transportation or stacking.
It is important to note that the grounded whiskers should be properly maintained and cleaned to ensure their effectiveness in dissipating static electricity. Over time, they may become contaminated with dust or other particles, reducing their ability to conduct electricity and discharge static. Regular cleaning and replacement of the whiskers may be necessary, depending on the specific application and environment.
Additionally, when using grounded whiskers to dissipate static electricity from plastic, it is crucial to consider safety precautions. Since static electricity can carry a high voltage, ensuring that the whiskers are properly grounded is essential to prevent any potential hazards. Proper grounding ensures that the static charge is safely directed to the ground, protecting both the plastic surface and any individuals handling the setup.
Overall, using grounded whiskers to cover the plastic surface is an effective method for dissipating static electricity. By providing a conductive path for the static charge to flow, the whiskers help neutralize the plastic's accumulated static electricity. This technique is particularly useful for addressing static issues in industrial or manufacturing settings, where plastic surfaces frequently come into contact with other materials, generating static electricity that needs to be safely and efficiently discharged.
