Static electricity on plastic is a common phenomenon in our daily lives and, at the same time, it causes various disruptions that impact everyday life, industry, and production. How can static electricity be removed from plastic? Let EuroPlas guide you through effective solutions to reduce and eliminate static electricity on plastic.

1. When does static electricity occur?

Static electricity is a surface phenomenon that occurs when two or more surfaces come into contact and then separate. This contact results in the separation of electric charges, meaning the transfer of negative electrons from one surface to another.

The magnitude of the charge (electric field intensity) depends on several factors, including:

• The material and its physical and electrical properties.
• Temperature.
• Humidity.
• Pressure.
• Separation speed.

The higher the pressure or separation speed, the greater the electric charge. This charge can only flow when in contact with a different electrostatically charged surface (potential difference). This surface can be a metal, water, or ionized air.

2. What makes plastics prone to static electricity formation?

Plastics are prone to static electricity formation for several reasons:

• Low electrical conductivity: Plastics are insulating materials, meaning they do not conduct electricity well. This makes it challenging for electrons to move from one plastic surface to another. When two plastic surfaces come into contact and then separate, electrons may become trapped on one surface, creating static electric charges.
• Low humidity: High humidity can assist electrons in moving more easily, reducing the risk of static electricity. On the other hand, low humidity can increase the static charge retention of plastics.
• Contact speed: High contact speed can generate more static charges compared to slow contact speed. This is because electrons have less time to move between plastic surfaces.

3. What happens when static electricity occurs on plastic?

Plastic is a common material in our everyday lives, used in various applications. Static electricity on plastic can lead to several consequences in production, industry, and daily life, including:

3.1. Impact on production and industry

• Fire Hazards: Static electricity can generate electric sparks, which are a leading cause of fires and explosions in environments prone to combustion, such as gasoline storage facilities and chemical plants.
• Product Defects: Static electricity can cause plastic products to attract dust, stick together, or be displaced, leading to defects. In the food industry, static electricity can cause food products to attract dust, bacteria, and reduce product quality. In the packaging industry, it can result in products sticking together, accumulating dust, or being displaced, leading to waste.
• Equipment Damage: Static electricity can damage sensitive electronic devices, like computers and phones. In electronic manufacturing, static electricity can harm electronic components, compromising product quality or even causing explosions.
• Human Safety Concerns: Static electricity can pose electrical shock risks to people, especially in low-humidity environments.

3.2. Impact on daily life

• Usability Challenges: Static electricity can make plastic products stick together, making them difficult to separate and use.
• Annoyance: Static electricity can produce small electrical sparks, crackling sounds, or sudden movements of plastic products, causing inconvenience to users.
• Human Safety Concerns: Static electricity can pose electrical shock risks to people, especially in low-humidity environments.

4. How to remove static from plastic?

You can try several methods how to remove static electricity from plastic, such as the following: 

4.1. Use anti-static spray

Anti-static sprays or solutions are designed to neutralize electric charges and can be sprayed onto the plastic surface to reduce the potential for static build-up. Follow the product instructions for proper usage and application. Anti-static sprays are commonly used in applications such as electronic manufacturing and assembling electronic components.

4.2. Increase humidity

Higher humidity levels can facilitate the movement of electrons, reducing the risk of static electricity. You can increase humidity in the environment by using misting machines or placing plastic in a humid environment. Placing a small water dish near the plastic surface can also add moisture to the air.

4.3. Grounding

Grounding plastic can help dissipate static electric charges. You can use anti-static wristbands or use metal grounding wires while touching the plastic surface. This helps balance the electric charges and reduces static charge accumulation.

4.4. Soft fabric cloth

Rubbing the plastic surface with a soft fabric cloth can help reduce static charges. The cloth contains small conductive particles that aid in removing static electricity from the plastic surface. The anti-static properties of the cloth can neutralize static charges on the plastic.

4.5. Anti-static cleaning agents

There are specialized anti-static cleaning products designed to clean and reduce static charges on plastic surfaces. These products can be found at electronic stores or online retailers.

4.6. Avoid synthetic materials

It's advisable to avoid using synthetic materials, like polyester or nylon, in applications sensitive to static electricity as they tend to generate more static charges. Consider using natural fabrics or materials instead of synthetic ones when cleaning or treating plastic surfaces.

It's important to note that the effectiveness of the methods to remove static from plastic can vary depending on factors such as the type of plastic, the level of static charge, and the specific application. It's advisable to test any cleaning or anti-static product on a small, inconspicuous area of the plastic surface before applying it extensively.

5. Do all types of plastics have anti-static properties?

The answer is no; not all plastics possess anti-static properties. Some plastics, such as PVC and PET plastics, are more prone to static electricity than other plastic types.

Anti-static plastics are those with good electrical conductivity, which helps reduce the risk of static charge accumulation. They are often used in applications sensitive to static electricity, such as electronics manufacturing and assembling electronic components.

Here are some common types of plastics with anti-static properties:

• ABS Plastic: ABS plastic is a thermoplastic with good anti-static properties. It is commonly used in applications such as electronic casings and toys.
• PC Plastic: PC plastic is a thermoplastic with good anti-static properties. PC plastic is often used in applications like computer casings and conduits.
• PTFE Plastic: PTFE plastic is the best thermoplastic with excellent anti-static properties. It is typically used in applications like insulating sheets and conduits.

To ensure that the plastic you are using is anti-static, you should check the manufacturer's technical specifications.
