In the entire production process of stretched PTFE microporous membrane, the stretching conditions are a very important influencing factor.
They will affect the thickness, average pore diameter and maximum pore diameter of the microporous membrane and all indicators related to pore performance.
? People have long noticed that polytetrafluoroethylene (PTFE), which has the most outstanding comprehensive properties among polymer materials, has excellent high and low temperature properties, outstanding chemical stability, as well as good dielectric properties and hydrophobicity. It is an ideal membrane material for separating microparticles under some harsh conditions.
The pore performance of ptfe microfiltration membrane is related to the size, removal rate and permeability of medium particles in the intercepted fluid in its application. It is a necessary performance data in development and application.
