1. Raw material selection and optimization
Select high-purity polytetrafluoroethylene resin:
Ensure that the impurity content in the raw material is extremely low, because impurities may reduce the electrical insulation performance of the material. High-purity polytetrafluoroethylene resin can provide a more stable molecular structure and reduce the possibility of charge conduction.
For example, when purchasing raw materials, choose a well-known brand and a polytetrafluoroethylene resin supplier with strict quality control to ensure the purity of the resin.


For example, surface-treated nano-silica fillers can be evenly dispersed in the polytetrafluoroethylene matrix to form a good insulation network and improve electrical insulation performance.

4. Environmental control
Moisture-proof measures:
PTFE sheets may absorb moisture in a humid environment, thereby reducing electrical insulation properties. Therefore, during storage and use, moisture-proof measures should be taken, such as placing them in a dry environment and using moisture-proof packaging.
