It is understood that the development of biological research and medicine urgently needs new technologies to solve the impact of environmental factors, which promotes the inevitability of the application of FFU filter membranes in clean rooms.
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, and good dielectric properties and hydrophobicity. It is an ideal membrane material for separating microparticles under some harsh conditions. However, the infusible and insoluble characteristics of PTFE have made the technology of manufacturing its microfiltration membrane difficult to solve for a long time, limiting its application and development. In the 1960s, DuPont first used Clean room FFU filter membranes are produced by uniaxial stretching. Although the size of the pores, porosity, and membrane strength are not suitable for use in microfilters, they have been widely used as sealing tapes in the future. In the mid-1970s, the United States successfully developed two-way PTFE Stretched microfiltration membranes were subsequently produced in Japan and Europe.
New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development and production of FFU dust-free workshop purification membranes and series of products. We have advanced ptfe membrane production lines, coating and composite production lines, which are at the domestic advanced level.
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.
