What is the current status of domestic research on PTFE flat membrane?

my country has tracked and studied the production and application of polytetrafluoroethylene fibers. Some of the research results listed below reflect the research progress of polytetrafluoroethylene.

At present, my country has formed the industrial production of 100% ptfe flat membrane. Polytetrafluoroethylene fiber has been used in long fiber woven base fabric, and short fibers are covered on the surface of the base fabric and processed into needle felt.

However, because PTFE fibers are prone to static electricity and have low friction coefficients, there are still problems such as difficulty in carding and web formation.

It is a high-tech enterprise specializing in the research and development, production and sales of polytetrafluoroethylene microporous membranes. It has advanced PTFE membrane production lines, coating and composite production lines, which are at the domestic advanced level.
