What is the reason for the resistance fluctuation of conductive rubber strips during use and how to investigate it?

Conductive rubber strips, as an important electronic material, play a crucial role in electromagnetic shielding, anti-static, and conductive connections. However, during use, conductive rubber strips may sometimes experience resistance fluctuations, which not only affect their conductivity but may also have adverse effects on the stability and reliability of the entire electronic device. This article will be combined with the information provided by Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand conductive rubber stripExplore the causes and troubleshooting methods of resistance fluctuations in conductive rubber strips.

Reasons for Resistance Fluctuations

1. material aging

   During the use of conductive rubber strips, due to prolonged exposure to physical and chemical factors, the rubber material may experience aging, resulting in decreased conductivity and increased surface resistance. Aging phenomenon is one of the main reasons for the fluctuation of resistance in conductive rubber strips.

2. Usage environment

   The resistance value of conductive rubber strips is closely related to environmental factors. For example, in high temperature and high humidity environments, rubber materials will soften, leading to an increase in surface resistance. In addition, temperature changes can directly affect the resistance value of conductive rubber strips, usually the higher the temperature, the greater the resistance.

3. forcing

   During the use of conductive rubber strips, they are often subjected to external forces such as gravity, tension, and compression, which can damage the surface of the conductive rubber strip, resulting in a decrease in conductivity and an increase in resistance.

4. Batch differences

   Different batchesConductive rubber stripDue to differences in production processes and material ratios, there may be fluctuations in the resistance value.

Troubleshooting methods

1. Check the usage environment

   Firstly, the usage environment of the conductive rubber strip should be checked to ensure that environmental factors such as temperature and humidity are within an appropriate range. For high temperature and high humidity environments, corresponding cooling and dehumidification measures should be taken.

2. Check the effect of external force

   Check whether the conductive rubber strip has been subjected to excessive external forces during use, such as strong tearing, rubbing, etc. If such problems exist, the installation method or protective measures should be adjusted to reduce external damage to the conductive rubber strip.

3. Check material aging

   For conductive rubber strips that have been used for a long time or have shown signs of aging, new conductive rubber strips should be replaced. Meanwhile, high-quality and long-lasting conductive rubber strips should be selected to reduce the risk of resistance fluctuations.

4. Batch testing

   For different batches of conductive rubber strips, resistance value testing should be conducted to ensure that the resistance value of each batch of conductive rubber strips fluctuates within the allowable range. If there are significant batch differences, timely communication should be made with the supplier to adjust the production process and material ratio.

5. Professional testing

   Using the four probe methodConductive rubber stripConduct volume resistivity testing to obtain more accurate resistance value data. By measuring multiple times and taking the average, the accuracy of the test can be improved. At the same time, the test results can be compared with the standard values to determine whether the resistance fluctuation of the conductive rubber strip is within the allowable range.
