PTFE membrane filter media "Tetratex"
When "Tetratex" is laminated, the base materials such as textiles and felt can also become "high-performance filter media."
PTFE (polytetrafluoroethylene) is specially processed to create a continuous porous membrane called "TetraTex Membrane," which has an extremely fine structure. Despite having very small pore sizes, it features a very high open area ratio. As a result, it excels in non-stick properties, self-lubrication, low friction, heat resistance, and chemical resistance. "TetraTex" is utilized as a "high-performance filter media" by laminating it onto substrates such as textiles and felt materials, and it is applied in a wide range of fields including next-generation energy, medical supplies, precision electronic components, industrial filters, and water treatment facilities. Enhanced Functions: - Breathability, filter bag life, dust collection efficiency, release performance Reduced Functions: - Exhaust dust, pressure loss, cleaning frequency, running costs, filter replacement frequency Case Studies: - Industrial bag filters (achieving high collection efficiency, release properties, durability, and cost-effectiveness) - Microfiltration (filters for various manufacturing processes such as dust, liquids, fermentation, sterilization, and process gases) - TetraTex Contact (FDA and EU regulatory certification. Filter material suitable for pharmaceutical and food processing applications)
