Publish Time: 2024-07-30
Conductive PPO, as a modified plastic material made by combining polyphenylene ether (PPO) base material with conductive filler, is deeply affected by the type of conductive filler. The type of conductive filler not only determines the conductive properties of Conductive PPO, but also has an important impact on its mechanical properties, processing properties and chemical resistance.
First, the type of conductive filler directly affects the conductive properties of Conductive PPO. Common conductive fillers include carbon black, metal fiber, metal powder (such as silver powder, copper powder), carbon nanotubes, etc. These fillers form a conductive network in the PPO base material, making the originally insulating PPO material conductive. Different types of conductive fillers have different conductive properties, so Conductive PPO with different fillers will also have different conductive properties. For example, silver powder is often used as a filler for high-end Conductive PPO due to its excellent conductivity and chemical stability, while carbon black is widely used in occasions where the conductive properties are not required because of its low cost.
Secondly, the type of conductive filler will also affect the mechanical properties and processing properties of Conductive PPO. Although some metal fillers have excellent electrical conductivity, they may increase the hardness and brittleness of the material, affecting the formability and plasticity during processing. New fillers such as carbon nanotubes can improve the mechanical properties and processing properties of the material while maintaining high electrical conductivity.
In addition, the type of conductive filler is also related to the chemical resistance of Conductive PPO. Some metal fillers may corrode or react in a specific chemical environment, thus affecting the overall performance of the material. Therefore, when selecting a conductive filler, it is necessary to fully consider the application environment and use conditions of the material.
In summary, the type of conductive filler has a crucial impact on the performance of Conductive PPO. When selecting a conductive filler, it is necessary to comprehensively consider multiple factors such as conductivity, mechanical properties, processing properties, and chemical resistance to ensure that the final product can meet specific application requirements.
