There are significant differences between conductive silicone and ordinary silicone in many aspects. These differences are mainly reflected in material composition, performance characteristics and application fields.
1. Material composition
Conductive silica gel: In addition to containing silica gel-based materials, it also adds a specific proportion of conductive agents, such as carbon black, silver powder, nickel-coated copper powder, etc. The addition of these conductive particles makes the conductive silica gel possess the conductive function.
Ordinary silica gel: It is made of pure organic silicon compounds and does not contain conductive agents and other ingredients, so it does not have conductive properties.
2. Performance characteristics
Conductive properties:
Conductive silicone: It has significant conductive properties and can be used in situations where conductive connections or electromagnetic shielding are required.
Ordinary silicone: does not have conductive properties and is mainly used in sealing, buffering, waterproofing, sound insulation and protection that do not require conductivity.
Hardness and toughness:
Conductive silicone: relatively hard, with a hardness generally between 50 degrees and 70 degrees, and relatively poor toughness.
Ordinary silicone: It is relatively soft, with a hardness usually between 10 degrees and 20 degrees, and good toughness.
Heat resistance:
Both have high heat resistance, but conductive silicone may have higher temperature resistance due to different material compositions and can maintain stable performance at higher temperatures.
Other properties:
Conductive silica gel also has good electromagnetic sealing and water vapor sealing capabilities, and can provide stable conductivity under a certain pressure.
Ordinary silicone can maintain stable performance in a variety of environments due to its excellent weather resistance, chemical stability and resilience.
3. Application fields
Conductive silicone: Mainly used in electronic devices that require conductive properties or electromagnetic shielding, such as touch screens, anti-static electronic equipment, electromagnetic shielding gaskets, etc. At the same time, it is also widely used in military and commercial fields, such as cold shrinkable cable accessories, keyboard keys, etc.
Ordinary silicone: is widely used in sealing, buffering, waterproofing, sound insulation and protection of various products, such as thermos bottle sealing rings, pressure cooker ring heat-resistant handles, building sealing materials, etc.
