Polytetrafluoroethylene membrane can also be called ptfe film, that is, ptfe ultra-wide membrane.
This material is one of the most widely used engineering materials in modern industrial production.
Today we will learn more about ptfe high temperature resistant filter membrane.
PTFE, which was born during World War II, was initially used to produce special military supplies. It was declassified after the war and used in civilian industry.
For a long time after decryption, the price of PTFE was still very expensive.
In order to retain the excellent quality of PTFE and reduce the amount of raw materials, the American Gore Company tried to stretch PTFE to increase the amount of air in it, and finally obtained a lighter and more flexible material – expanded polytetrafluoroethylene. (ePTFE).
PTFE ultra-wide membrane has a three-dimensional mesh structure with no through holes.
The porosity and pore size distribution are important indicators for measuring membranes.
The porosity of Teflon membrane is generally between 80% and 95%.
High porosity will increase ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
Usually, membrane thickness is not an indicator for membrane evaluation. If the membrane thickness is too thick, it will easily cause problems such as low air permeability and high operating pressure.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The materials of the ptfe ultra-wide membrane products produced by our company are all imported raw materials, with high uniformity, stable performance and good air permeability.
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.
