Antistatic TPU is very common in industry and daily life, but the application of conductive TPU is relatively limited. The anti-static properties of TPU are attributed to its lower volume resistivity, typically around 10-12 ohms, which may even drop to 10 ^ 10 ohms after absorbing water. According to the definition, materials with a volume resistivity between 10 ^ 6 and 9 ohms are considered anti-static materials.
Anti static materials are mainly divided into two categories: one is to reduce surface resistivity by adding anti-static agents, but this effect will weaken after the surface layer is erased; Another type is to achieve permanent anti-static effect by adding a large amount of anti-static agent inside the material. The volume resistivity or surface resistivity of these materials can be sustained, but the cost is relatively high, so they are used less.
Conductive TPU typically involves carbon based materials such as carbon fiber, graphite, or graphene, with the aim of reducing the material’s volume resistivity to below 10 ^ 5 ohms. These materials usually appear black, and transparent conductive materials are relatively rare. Adding metal fibers to TPU can also achieve conductivity, but it needs to reach a certain proportion. In addition, graphene is rolled into tubes and combined with aluminum tubes, which can also be used for conductive applications.
In the past, anti-static and conductive materials were commonly used in medical devices such as heartbeat belts to measure potential differences. Although modern smart watches and other devices have adopted infrared detection technology, anti-static and conductive materials still have their importance in electronic component applications and specific industries.
Overall, the demand for anti-static materials is more extensive than that for conductive materials. In the field of anti-static, it is necessary to distinguish between permanent anti-static and surface precipitation anti-static. With the improvement of automation, the traditional requirement for workers to wear anti-static clothing, shoes, hats, wristbands and other protective equipment has decreased. However, there is still a certain demand for anti-static materials in the production process of electronic products.
