Understanding Anti-Static Rubber
Anti-static rubber is a specialized material designed to dissipate static charges. Unlike insulators that trap static electricity, anti-static rubber allows the charges to safely flow away, preventing buildup and potential harm. This property is achieved through the incorporation of conductive additives into the rubber matrix. The effectiveness of the anti-static properties is measured by surface resistivity, which indicates how readily a material allows electric current to flow across its surface. Lower surface resistivity indicates better anti-static performance.
Technical Features of Anti-Static Rubber
The performance of anti-static rubber varies depending on its composition and manufacturing process. Several key technical parameters distinguish different types. These parameters are crucial for selecting the appropriate rubber for a specific application. Companies like those listed on us.metoree.com offer a wide range of anti-static agents for rubber manufacturing.
| Feature | Unit | Typical Range | Significance |
|---|---|---|---|
| Surface Resistivity | Ω/sq | 106 – 109 Ω/sq | Lower values indicate better static dissipation. |
| Volume Resistivity | Ω·cm | 1010 – 1012 Ω·cm | Measures resistance to current flow through the material’s volume. |
| Shore Hardness | Shore A | 60 – 70 | Indicates the rubber’s stiffness and resistance to deformation. |
| Tensile Strength | MPa | 3 – 10 | Measures the rubber’s resistance to tearing and stretching. |
| Elongation | % | 100 – 300 | Indicates the rubber’s ability to stretch before breaking. |
| Temperature Range | °C | -20°C to +70°C (or higher depending on type) | Defines the operating temperature limits of the rubber. |

FAQs
1. What is the difference between conductive and dissipative anti-static rubber?
Conductive rubber offers higher conductivity and dissipates static charges more rapidly. Dissipative rubber offers moderate conductivity, suitable for applications requiring less aggressive static control and greater flexibility.
2. How is the effectiveness of anti-static rubber measured?
The primary measure is surface resistivity, expressed in ohms per square (Ω/sq). Lower values indicate better anti-static performance. Volume resistivity is another parameter that measures the material’s resistance to current flow through its volume.
3. What are the common applications of anti-static rubber sheets in China?
Common applications include work surfaces in electronics manufacturing, flooring in cleanrooms, protective mats for sensitive equipment, and packaging for electronic components. Companies like www.jingkairubber.com specialize in supplying these sheets.
4. What factors should be considered when choosing anti-static rubber?
Consider the required level of static protection (surface resistivity), operating temperature range, chemical resistance, mechanical properties (tensile strength, elongation, hardness), and cost.
5. Are there any safety considerations when using anti-static rubber?
While generally safe, proper grounding procedures are essential when using conductive rubber to ensure effective static discharge. Always consult the manufacturer’s guidelines for safe handling and installation.
