Grid Anti-Static Silicone Sheet: What Is It Used For And What Are Its Advantages?

Grid Anti-Static Silicone Sheet: What Is It Used For and What Are Its Advantages?

1. What Is a Grid Anti-Static Silicone Sheet?

A grid anti-static silicone sheet is a functional silicone sheet featuring a regular grid structure formed on the surface or within the silicone base material, combined with stable anti-static performance.

It retains the key advantages of silicone materials—such as high temperature resistance, flexibility, and aging resistance—while effectively controlling electrostatic buildup through a combination of grid structure design and anti-static formulation.
This makes it widely used in electronics manufacturing, automation equipment, and precision industries.

In simple terms:
Durable silicone + structural grid support + anti-static performance = grid anti-static silicone sheet

2. Why Use a Grid Structure?

Compared with flat silicone sheets, the grid design serves clear functional purposes rather than aesthetics:

1) Even pressure distribution
The grid structure helps disperse pressure evenly, reducing localized stress and protecting delicate components or product surfaces.

2) Improved anti-slip and positioning stability
The grid increases friction, preventing movement during conveying, placement, or pressing processes.

3) Better ventilation and heat dissipation
Grid gaps promote air circulation, reducing heat or gas accumulation—ideal for continuous-operation equipment.

4) Longer service life
More uniform stress distribution reduces material fatigue and deformation, ensuring stable long-term performance.

3. How Is Anti-Static Performance Achieved?

Anti-static silicone sheets typically control static electricity through:

• Adding anti-static or conductive fillers (such as conductive carbon black or anti-static agents)

• Optimizing the silicone formulation to maintain controlled surface resistivity

• Creating stable static discharge pathways to prevent sudden electrostatic buildup

Typical surface resistivity ranges:

• 10⁶–10⁹ Ω: Anti-static grade

• 10³–10⁵ Ω: Conductive grade (customizable)

Actual parameters should be defined according to the operating environment and relevant standards (such as ESD requirements).

4. Key Features of Grid Anti-Static Silicone Sheets

✔ Stable anti-static performance, reducing electrostatic attraction and discharge risks
✔ Excellent heat resistance (continuous operation up to approx. 200°C)
✔ Soft and elastic, non-damaging to product surfaces
✔ Resistant to aging and ozone, suitable for long-term use
✔ Grid size, thickness, hardness, and color can be customized

5. Typical Applications

Grid anti-static silicone sheets are commonly used in:

• Electronics manufacturing: PCB trays, electronic component cushioning pads

• Automation equipment: Conveyor anti-slip pads, positioning pads

• Semiconductor industry: Wafer and precision component surface protection

• Packaging and inspection stations: Anti-static workbench mats, fixture pads

• Precision assembly lines: Preventing electrostatic damage to sensitive components

6. Key Parameters to Consider When Selecting

When selecting or customizing a grid anti-static silicone sheet, it is recommended to confirm:

• Surface resistivity range (Ω)

• Hardness (Shore A)

• Thickness and grid dimensions

• Temperature resistance requirements

• Required certifications (RoHS, REACH, ESD testing, etc.)

• Operating conditions (high humidity, high temperature, continuous operation)
