Electrical Resistance Target
Common static-dissipative targets such as 10^6 to 10^9 ohms can be reviewed, with test conditions confirmed before production.
Custom Anti-Static Silicone Rollers
Fecision manufactures custom anti-static silicone rollers for semiconductor, PCB, optical film, cleanroom handling, and precision electronics lines. Each roller is built around the contact surface, grounding path, line speed, temperature, and dimensional requirements of your equipment.
- Custom OD, face length, shaft design, hardness and color
- ESD-dissipative silicone options from 10^6 to 10^9 ohms
- Precision ground roller surface for stable contact and low vibration
What is Anti-Static Silicone Roller?
An anti-static silicone roller is a custom rubber-covered roller designed to reduce static buildup while maintaining controlled contact with sensitive electronic, film, or panel surfaces.
In high-value production lines, a roller can influence particle control, static buildup, surface marking, material release, and transport stability. Standard rubber or plastic rollers may generate triboelectric charge, attract dust, or leave residue when they run against films, tapes, panels, or conveyor surfaces.
Custom anti-static silicone rollers use a silicone surface bonded to a machined metal core. For ESD-sensitive processes, conductive or static-dissipative fillers can be distributed through the silicone compound so the roller surface remains more consistent through wear than a temporary surface coating.
Why Use Anti-Static Silicone Rubber For Precision Rollers?
The roller covering material should protect the product and keep the line stable. We review ESD behavior, cleanliness, temperature exposure, release behavior, hardness, and roller geometry together.
For precision rollers, anti-static performance should come from the rubber compound itself rather than only a temporary coating. Conductive or static-dissipative additives are dispersed through the silicone matrix so the roller can keep a more stable electrical path as the surface is used and reground.
Silicone also brings soft contact, heat resistance, and natural release behavior for adhesive films, OCA, PCB, display panels, and printer feed media. The right compound depends on the substrate, grounding path, measurement method, contact pressure, temperature, and cleanliness requirement.
Filler And Cleanliness
Carbon-filled grades are common, while low-particle or carbon-free options may be reviewed when black transfer or cleanroom contamination is a concern.
Hardness And Surface Feel
Shore A hardness, tack, surface finish, and rubber thickness are matched to avoid scratching, sticking, wrinkling, or unstable feeding.
Temperature And Aging
Silicone helps support heat exposure, but the final compound should be checked against line temperature, chemical contact, UV exposure, and expected service life.
Custom Anti-Static Silicone Roller Specifications
These values are starting points for quotation. Final specifications depend on the core design, silicone compound, roller size, surface finish, and equipment interface.
| Specification | Custom Options |
|---|---|
| Metal core | Aluminum, stainless steel, carbon steel, or customer-supplied shafts and cores. |
| Outer diameter | Custom sizes, commonly from 20 mm to 250 mm or larger depending on equipment design. |
| Face length | Custom length from compact guide rollers to long web-handling rollers, including lengths up to 3,000 mm when feasible. |
| Electrical resistance | Static-dissipative targets such as 10^6 to 10^9 ohms can be reviewed for ESD-sensitive lines. |
| Temperature range | Typical silicone roller applications can be reviewed from -40°C to +200°C, depending on compound and exposure time. |
| Color | Black for many conductive grades, with dark blue or custom colors available when the formulation allows. |
| Concentricity / runout | Precision grinding can support tight runout targets such as ≤0.02 mm on suitable roller designs. |
| Surface finish | Smooth, matte, tack-controlled, release-focused, or application-specific finishes. |
Anti-Static Silicone Roller Manufacturing Process
Silicone overmolding or rubber covering is a central step, but the finished roller depends on the complete process chain.
A typical custom roller program starts with metal core machining and surface preparation. The silicone is then bonded to the core through molding or rubber covering, cured, post-cured when required, and precision ground to the final OD and surface finish.
For ESD and cleanroom applications, we also review grounding design, surface resistance, visual condition, hardness, dimensional accuracy, cleaning, and packaging before shipment.

Anti-Static Silicone Roller Design
A drawing is the best starting point. If you do not have a finished drawing yet, these details help us review feasibility and material direction.
What will the roller touch?
Confirm whether the substrate is wafer-adjacent material, PCB, optical film, adhesive tape, OCA, PET, PI, copper foil, or packaging film.
What electrical behavior is needed?
Define the surface resistance target, grounding method, measurement condition, and whether static dissipation must remain stable after wear.
What contact force is acceptable?
Line pressure, hardness, rubber thickness, and surface tack should be matched so the roller does not wrinkle, stretch, mark, or pull the substrate.
What accuracy does the line require?
Share OD tolerance, face length, shaft details, runout target, balance requirement, speed, and any vibration or tracking issues from the current roller.
Applications For Anti-Static Silicone Rollers
Anti-static silicone rollers are used where the product surface is valuable, sensitive, adhesive, or easily damaged by static and hard contact.
