Clean room FFU filter membrane is a microporous film produced using polytetrafluoroethylene dispersion resin through special processes such as premixing, extrusion, calendering, and biaxial stretching.
The surface morphology of the microporous film is a spider web-like microporous structure.
Pores are formed between the microfibers, and the arrangement direction of the microfibers is basically parallel to the stretching direction; the junction of the fiber bundles is the node, which is formed by the entanglement of many microfibers.
The clean room FFU filter membrane is an asymmetric membrane, and the micropore sizes are different on the front and back sides of the membrane.
The cross-sectional micropore size of the membrane is larger than the micropore size on its surface, and the vertical and horizontal micropore sizes are also different, with the longitudinal micropores being larger than the transverse ones.
Using the unique node fibrillarity, smooth surface, chemical resistance, air permeability and water impermeability, large air permeability, flame retardant, high temperature resistance, strong acid and alkali resistance and other characteristics of the ptfe filter membrane, it can be used for atmospheric dust removal, air purification, etc. .
Suzhou New Material Technology Co., Ltd. is a manufacturer specializing in the research, development and production of polytetrafluoroethylene materials. After years of painstaking research and development, the company not only has strong research and development capabilities, complete testing methods and domestically advanced Experimental equipment has also attracted a large number of outstanding technical talents.
