The ptfe hydrophobic film is almost resistant to the intrusion of all acids and alkalis and other chemical substances, and has outstanding non-stickiness, exceptional lubricity, excellent electrical insulation properties, aging resistance and radiation resistance, minimal water absorption and other characteristics.
Widely used in petrochemical, machinery, electronics, electrical appliances, construction, textile and many other fields.
PTFE hydrophobic membrane is made by special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.
The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.
It has high filtration efficiency, good filtration performance and small membrane pore size, which can meet the filtration efficiency level requirements of air filters.
?The polytetrafluoroethylene microporous membranes produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the quality of the microporous membrane. quality.
