How to make PTFE single-component clothing membrane and what is its filtration efficiency?

PTFE single-component clothing film is made through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.

Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction, and at the same time, the length of the fibrils Increase.

The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is 0.5~1.0nm.

It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.

The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
