Polytetrafluoroethylene (ptfe) is well known to everyone. It is a material that is acid and alkali resistant and almost insoluble in all solvents. In addition, ptfe is temperature-resistant, has an extremely low friction coefficient, and has self-cleaning characteristics. It is an ideal material for filtration. For more details, I will take you to the ptfe microporous membrane manufacturer to learn more.
Currently, ptfe microporous membrane manufacturers generally use granular polytetrafluoroethylene as raw materials for PTFE products Vinyl resin is industrially produced by suspension polymerization or emulsion polymerization, so PTFE resin can be divided into suspension resin, dispersion resin and resin dispersion.
The molecular weight and crystallinity of PTFE dispersion resin are generally higher than those of suspension resin, and the crystallinity of dispersion resin after sintering is greater, and the temperature is slightly higher than the melting point. High strength can be obtained by sintering at low temperature, and the bending fatigue life of dispersed resin is 2300 times that of suspended resin. Therefore, the raw material of PTFE microporous membrane is generally made of dispersed resin and combined with corresponding processes.
ptfe microporous membrane manufacturerPTFE microporous membranes adopt special processes and undergo calendering, extrusion, and two-way drawing. Compared with other filter materials, the filter membrane made by stretching and other methods has a higher PF value and good filtration performance. The membrane pore size is small, and the material has undergone high-temperature heat setting treatment, and the microporous structure is stable, so it can well block dust particles at high wind speeds. At the same time, the material has strong hydrophobicity, non-adhesion, corrosion resistance, thermal stability and good mechanical properties. Therefore, it can be washed with water to restore its performance and achieve repeated use, greatly extending its service life and saving costs.
