The clean room high-efficiency filtration membrane is made of polytetrafluoroethylene as the main raw material and adopts a wet molding process. It has the characteristics of uniform fiber distribution, large dust holding capacity, low resistance, and high strength. It is an ideal air filtration material.
The technical indicators of filter paper can be mainly divided into two aspects. One is the filtration characteristics of the filter paper, and the other is the physical properties.
Filtration characteristics include air permeability, air resistance, maximum pore size, and average pore size.
Physical properties include basis weight, thickness, stiffness, corrugation depth, bursting strength, resin content, etc.
