Nano alumina is a common ceramic material with excellent mechanical properties, conductivity, and wear resistance. Adding nano alumina to polytetrafluoroethylene and polyvinylidene fluoride can improve the mechanical properties, strength, and rigidity of PVDF and PTFE.

Specifically, nano alumina CY-BZ10 can increase the rigidity of PVDF and PTFE, and improve their wear resistance, impact resistance, and heat resistance. In addition, alumina can also prevent PVDF and PTFE from deforming at high temperatures, maintaining their shape and size stability. Therefore, it is necessary to add an appropriate amount of nano alumina in the production of PVDF and PTFE products.
