ptfe waterproof and breathable membrane is a waterproof material made of polymer materials, and it not only has good waterproofness but also good breathability and sealing properti…

Curing is usually performed under a certain tension to ensure pore formation and dimensional stability of the film. Curing temperature has a great impact on the pore size and poros…

Because the exterior lights of a car are almost always exposed, it is inevitable that a lot of bad weather will affect the lights of the car, such as water mist from rain and snow …

Experiments found that heat setting temperatures below 300°C have little improvement in stability, while temperatures above 400°C will seriously reduce the crystallinity, which wil…

The transverse expansion speed also affects the structure of the PTFE waterproof and breathable membrane. The higher the transverse expansion speed, the greater the porosity, while…

Looking at all current fiber fabrics, it is difficult to meet the waterproof and liquid barrier properties required by protective clothing standards. In order to solve this problem…

The transverse stretching stage is a key step in controlling the microporous structure and thickness of ptfe waterproof and breathable membrane. During the transverse stretching pr…

PTFE waterproof and breathable membrane can easily stretch out fibrils and nodes at a lower temperature (35°C), but when the strain reaches 25%, the base tape breaks and the tensil…

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 f…
