PTFE material has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation, electrically insulated wire, hydrophobicity, non-toxicity, high lubrication, non-adhesion, weather resistance, and chemical resistance and many other features.
Therefore, ptfe black membrane is widely used in air filtration, aviation, electronics, electrical appliances, chemical industry, machinery, construction, textile, medicine and many other fields.
Globally, well-known PTFE membrane manufacturers include Saint-Gobain of France, Gore of the United States, Donaldson of the United States, Sumitomo of Japan, Pall of the United States, MKL of the United States, Taconic of the United States, Porex of the United States, Zeus of the United States, ZTE Chemicals of Japan, and Millipore of the United States. , BHA of the United States, Nitto Denko of Japan, Daikin of Japan, etc., mainly American and Japanese companies.
Compared with international giants, my country’s PTFE membrane manufacturers still have certain gaps in terms of capital, scale, and high-end product productivity, and they need to continue to improve in the future.
The ptfe black membrane material has a microporous structure with staggered fibers, achieving surface filtration and dust removal efficiency reaching 99.9%~99.999% for some extremely small particles with a diameter of 0.1um-0.3um.
The porosity can reach 80%~90%, it has strong hydrophobicity, low surface energy, and good non-adhesive ability. It can effectively remove dust accumulated on the surface. It can restore the performance by washing with water or backflushing, and greatly extends the service life.
The ptfe black membrane is prepared using a unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
