Static Dissipative vs Conductive: What is the Difference?

August 20, 2024 | General

Static dissipative and conductive materials are essential in industries where electrostatic discharge (ESD) protection is crucial. However, there’s often confusion surrounding static dissipative vs conductive materials.

Both are designed to prevent the build-up and discharge of static electricity, but they achieve this in different ways.

Understanding their differences is crucial to selecting the right ESD protection measures for specific applications. By choosing the appropriate material, industries can ensure the safety and reliability of their electronic systems.

We explore the key differences between these after a brief comparison of their definitions to help you get a better understanding.

From there, you should be able to choose the right solution to your needs.

Static dissipative vs conductive: a brief comparison

Before we delve deep into how the benefits and uses of the two compare, it’s worth defining the two:

What does static dissipative mean?

The term “static dissipative” pertains to the capacity of a substance or an item to hinder or lessen the accumulation of static electricity. When two substances make contact or rub against each other, electrons are exchanged, resulting in the formation of a static charge.

What does conductive mean?

When a material is classed as “conductive”, it means it has the ability to transfer heat or electricity easily. Materials that are conductive allow the flow of electrons or heat through them. The conductivity of a substance is determined by the arrangement and mobility of its atoms or molecules.

But what does static conductive mean?

Static conductive refers to the ability of a material to conduct or dissipate static electricity. It means that the material has low resistance to the flow of electric charges, allowing them to move across its surface and into the ground quickly. This property is important in industries where static electricity can pose a risk, such as electronics manufacturing or explosive environments.

What is the difference between static dissipative and conductive materials?

 

The main difference between static dissipative and conductive materials is their ability to control static electricity. Conductive materials have very low electrical resistance and effectively and rapidly conduct electricity to the ground. Static dissipative materials have higher electrical resistance and slowly and safely dissipate static charges, minimizing electrostatic discharge risk.

With these core differences in mind, let’s delve a bit deeper so you can see how each of these might apply to your business or industry…

Electrical resistance

Static dissipative materials and conductive materials both have properties that make them desirable for specific applications when it comes to electrical resistance.

However, they differ in terms of their ability to conduct or dissipate static charge.

Conductive materials, such as metals, have a low resistance, meaning they allow the flow of electric current easily. As such, they’re efficient in conducting electricity and redirecting static charges away from sensitive components.

On the other hand, static dissipative materials have a higher resistance compared to conductive materials, allowing for a slower flow of electric current. This property makes them ideal for applications where static build-up needs to be dissipated at a controlled rate rather than instantaneously.

In addition, static dissipative materials limit the flow of current, preventing any rapid discharge that could harm electronic components.

While both types of materials have their uses, the choice depends on the specific requirements of the application at hand:

• Conductive: when complete dissipation of static charges is required
• Static dissipative: when a controlled discharge is needed

Which is more effective in dissipating static electricity? Static dissipative or conductive?

In dissipating static electricity, both static dissipative and conductive materials play essential roles. However, the effectiveness of each type depends on the specific requirements of the situation.

Static dissipative materials, with electrical resistance ranging from 10^9 to 10^12 ohms, are often used in environments where the discharge of static electricity needs to be managed to prevent damage to sensitive electronic components.

On the other hand, conductive materials, with electrical resistance less than 10^5 ohms, are commonly used in situations where a rapid dissipation of static charge is necessary, such as working with explosive materials.

Cost

Static dissipative materials are generally less expensive than conductive materials. This is because static dissipative materials do not require a high level of conductivity, which is more expensive to achieve.

Conductive materials, on the other hand, need to have a lower resistance to effectively conduct electricity and eliminate static charges. This higher level of conductivity requires more specialized manufacturing processes and materials, leading to increased costs.

Additionally, conductive materials might also require additional safety measures, such as grounding systems, to ensure their effectiveness, further contributing to their higher cost.

However, it is important to weigh the cost against your specific requirements to determine the most suitable option.

Similarities: static conductive vs static dissipative

One similarity of static conductive vs static dissipative is that they’re both designed to facilitate the safe discharge of static electricity.

Static conductive materials are able to conduct an electrical charge and provide a pathway for the static electricity to flow, thereby preventing potential damage or injury.

Similarly, static dissipative materials have a higher electrical resistance than conductive materials but still allow for the controlled discharge of static electricity.

Another similarity is that both static conductive and static dissipative materials are typically made using additives that enhance their electrical properties. These additives, such as carbon or metallic particles, help to decrease the electrical resistance and create a path of least resistance for the static electricity.

Additionally, both types of materials are commonly used in a range of industries, including electronics, automotive, and manufacturing, where the presence of static electricity can be detrimental to sensitive equipment or processes.

Is PVC static dissipative?

PVC isn’t inherently static dissipative. It is a thermoplastic material that tends to generate static electricity during handling and processing.

However, manufacturers have developed various additives and treatments to enhance PVC’s static dissipative properties. These additives can reduce or eliminate the build up of static charges on the surface of PVC materials, making them suitable for applications where static discharge could pose a risk, such as in electronic manufacturing or cleanroom environments.

It is important to note that the effectiveness of these additives may vary depending on factors such as temperature, humidity and the specific formulation of the PVC.

Is polypropylene a static dissipative?

Polypropylene isn’t a natural static dissipative material. It’s a non-conductive material, meaning it does not readily allow the flow of electrical charges.

However, as with PVC, the addition of certain additives or modifications can make polypropylene “static dissipative.”

Static dissipative polypropylene is commonly used in applications where static electricity can pose a risk, such as in electronic manufacturing or cleanroom environments.
