The ptfe black base tape membrane has a node-fine fiber structure, forming hundreds of millions of micropores per unit area, which can effectively intercept dust in the air. It is very suitable for air purification fields, such as vacuum cleaner applications, and the high performance of air filtration membranes. The breathable performance and high interception efficiency enable the vacuum cleaner to not only effectively intercept dust particles, but also achieve a maximum accuracy of over H14 (99.995%). Since the micropore diameter is tens of thousands of times larger than water molecules and hundreds of times smaller than water droplets, it has excellent Moisture permeable, breathable and waterproof.
