When the stretching ratio is small, the length of the microfibers is smaller and the orientation is lower. When the stretching ratio is larger, micropores with a more uniform size distribution can be obtained.
Although the degree of microfiber orientation increases, the larger microfiber size causes the microfibers to de-orient during the subsequent heat setting process, thus reducing the strength.
It is a ptfe biaxially stretched film manufacturer specializing 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.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
