Anti-Static/Conductive Rubber Rollers
Anti-static and conductive rubber rollers are mainly used for charge control, contamination reduction, surface protection, and stable running in electrostatic-sensitive operating conditions.
They are commonly used in contact positions involving films, separators, foils, nonwovens, and other materials that are prone to static buildup, dust attraction, sticking, poor release, or surface damage.
In many projects, the visible problems are dust attraction, sticking, material pickup, localized contamination, surface scratching, or unstable guiding. In many cases, these issues are closely related to static control.
The point is not simply whether the roller is conductive, but whether the roller surface is built for the actual static-control needs of that line position and material.
If you already have drawings or current dimensions, you can send them to us directly.
If not, you can also send us the roller position and the current problem first, and we can help you evaluate the direction.
Anti-Static, Conductive, and Static-Dissipative: What Is the Difference?
Anti-Static
Anti-static is more focused on reducing static buildup and lowering the impact caused by static.
It is more commonly used in applications where the goal is to reduce dust attraction, sticking, surface contamination, marks, and unstable running.
Conductive
Conductive is more focused on dissipating electrical charges more quickly.
If your roller position has a clear requirement for charge dissipation, this direction is usually more worth considering.
Static-Dissipative
Static-dissipative usually sits between the two.
It is not fully insulating, and it is not simply about stronger conductivity. Instead, it helps keep the roller surface in a more balanced static-control condition.
When selecting this type of roller, the first thing to look at is usually not the name itself, but whether you need:
- reduced static buildup
- faster charge dissipation
- more stable static dissipation
Common Material Routes
Anti-static / conductive rollers are not based on one single material.
More commonly, conductive, anti-static, or static-dissipative properties are built into different base materials according to the actual operating condition. Below are some of the more common material routes.
Conductive / Anti-Static Silicone Rollers
If your project requires static control, surface protection, and temperature stability at the same time, this is usually one of the first options to consider.
It is more commonly used in:
- positions with higher temperatures or noticeable temperature fluctuations
- materials with more sensitive surfaces
- applications requiring gentler contact and cleaner surface handling
For standard applications, silicone-based options can typically be developed to the 10⁶–10⁷ ohm level, while maintaining good surface protection and temperature stability.
Typical specifications may also include:
- hardness around 65 Shore A
- operating temperature around -40°C to +200°C
For projects with higher heat resistance and stronger conductivity requirements, upgraded conductive silicone options can also be developed to reach the 10⁵ ohm level.
Higher-grade versions may also support:
- hardness around 65 Shore A
- operating temperature around -54°C to +260°C
Conductive / Anti-Static Polyurethane Rollers
If your project requires static control together with higher wear resistance, support, service life, and stable continuous running, polyurethane is often a strong option.
It is more commonly used in:
- positions with higher mechanical load
- applications with longer running time
- projects that require both static control and better wear performance
For standard applications, polyurethane-based options can typically be developed to the 10⁷–10⁸ ohm level, while maintaining good wear resistance, support, and running stability.
For projects with higher electrical-performance requirements, reinforced or upgraded polyurethane solutions can also be developed to reach the 10⁵ ohm level.
Typical specifications may also include:
- hardness around 82 Shore A
- operating temperature around -30°C to +80°C
Conductive / Anti-Static NBR Rollers
If your application involves static-control requirements together with oils, inks, adhesives, or certain printing / coating contact conditions, the NBR route is usually worth considering.
It is more commonly used in:
- positions requiring oil resistance
- positions involving ink or adhesive contact
- projects that need static control without moving too far away from conventional industrial rubber solutions
The nitrile route can also be used for anti-static / conductive rollers. It offers a good balance of static-control capability, mechanical strength, wear resistance, and resistance to mineral oils.
For standard applications, NBR-based options can typically be developed to the 10⁶–10⁷ ohm level, while maintaining good oil resistance, wear resistance, and running stability.
For projects with higher electrical-performance requirements, upgraded NBR solutions can also be developed to reach the 10⁵ ohm level, depending on the target and operating condition.
Typical nitrile-based references may also include:
- hardness around 70 Shore A
- operating temperature around -30°C to +100°C
Conductive / Anti-Static EPDM Rollers
If your project places more importance on environmental stability, weather resistance, ozone resistance, and long-term running performance, the EPDM route is usually more suitable.
It is more commonly used in:
- open environments
- long-term running positions
- applications that are more sensitive to environmental changes
For standard applications, EPDM-based options can typically be developed to the 10⁶–10⁷ ohm level, while maintaining good environmental stability.
For projects with higher electrical-performance requirements, they can also be developed to reach the 10⁵ ohm level.
Typical specifications may also include:
- hardness around 65 Shore A
Other Composite Routes
In addition to silicone, polyurethane, NBR, and EPDM, some projects also use neoprene or other special compound routes to balance static control with other environmental requirements.
Besides conventional anti-static / conductive roller solutions, some projects also use modified, reinforced, or composite compound routes to meet more demanding operating conditions.
Key Parameters
1. Electrical Performance Targets
The first things to check are usually:
- surface resistance
- volume resistivity
- whether the target is anti-static, conductive, or static-dissipative
- whether grounding needs to be used together with the roller
If you already have a target resistance value, you can communicate with us directly based on that target. Different test methods, test voltages, humidity conditions, and surface states can all affect the final resistance reading.
2. Surface Condition
Surface condition also affects actual performance, for example:
- whether dust is easily attracted
- whether the material tends to stick
- whether separation is affected
- whether surface marks are more likely to appear
3. Operating Conditions
These usually also need to be checked together:
- line speed
- tension condition
- contact material
- temperature and humidity environment
- whether cleanliness is critical
- whether surface protection is highly important
Modified and Reinforced Compound Routes
Conventional anti-static / conductive solutions can cover most electrostatic-sensitive operating conditions.
If your project requires higher performance in electrical stability, wear resistance, heat resistance, surface protection, or long-term running consistency, modified, reinforced, or composite compound routes can also be evaluated further.
These routes are usually more suitable for:
- applications requiring tighter electrical-performance control
- applications requiring both static control and higher wear resistance
- applications requiring both static control and higher heat resistance
- applications with higher requirements for cleanliness, surface protection, or environmental stability
The main optimization goals usually include:
- more stable electrical performance
- better wear resistance and service life
- higher or more stable temperature resistance
- more suitable contact and release performance
- compound solutions better matched to specific environments

Customizable Options
Anti-static rollers can usually be adjusted according to project requirements in the following aspects:
- Material direction: anti-static, conductive, static-dissipative, or composite compound direction
- Hardness: can be adjusted according to contact pressure, surface requirements, running speed, and support requirements
- Surface finish: smooth, precision-ground, matte / satin, or other surface directions depending on the project
- Cover and structure: cover thickness, roller diameter, face length, shaft construction, shaft-end details, and fit requirements can all be confirmed according to the project
- Basis for production: can be confirmed based on drawings, existing rollers, samples, or actual operating conditions
