Waterproof and breathable materials, also known as breathable materials, refer to a material that can prevent liquid water from passing or penetrating, while at the same time allowing gas or water vapor to pass through.
There are many kinds of this material on the market, and ptfe waterproof and breathable membrane is one of them.
PTFE waterproof and breathable membrane is made by 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. At the same time, the fibrils The length increases.
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.
