Original product description
This TDL-series polypropylene meltblown membrane is supplied as roll media for liquid-filtration use. The available range is divided into three groups: classic micro-grade media, TDL-II micro-grade media, and uncalendered coarse-grade media.
Buyers can compare grades by mean pore size, basis weight, permeability, thickness, roll length, and available width. The classic series includes TDL-1, TDL-2, TDL-3, TDL-5, TDL-7, and TDL-10. Their stated mean pore sizes run from 1 μm ±10% to 10 μm ±10%.
All are listed in 500 m rolls and widths of 10, 20, or 40 inches. Depending on grade, listed basis weights range from 50 ±10% to 100 ±10% g/m², while listed thickness ranges from 0.13 to 0.20 mm. The TDL-II series includes grades from TDL-05-II through TDL-10-II.
Listed mean pore-size ranges extend from 0.4–0.6 μm to 5.0–7.0 μm. TDL-05-II and TDL-075-II are listed as 250 m rolls in 10- or 20-inch widths. The remaining TDL-II grades are listed as 500 m rolls in 10-, 20-, or 40-inch widths.
Grade-specific basis weights range from 45 to 110 g/m², each with a stated ±10% tolerance, and listed thickness ranges from 0.14 to 0.26 mm. For larger pore sizes, the uncalendered coarse-grade range includes TDL-13, TDL-15, TDL-18, TDL-20, and TDL-30. Their stated mean pore sizes range from 13 μm ±10% to 30 μm ±10%.
Listed basis weights are 30–50 g/m², roll lengths are 600 or 800 m depending on grade, and available width is stated as up to 240 cm. Procurement questions to confirm: Ask for the current technical data sheet for the exact grade and confirm whether pore size is a mean value or a filtration rating for your application.
Verify liquid compatibility, operating temperature, allowable differential pressure, filtration efficiency, flow performance, and expected service life under actual process conditions.
Also confirm roll-width tolerance, basis-weight tolerance, thickness tolerance, roll core and winding details, packaging, lot traceability, sample availability, customization limits, and current production lead time.
If the media will be pleated, welded, laminated, or used in food, drinking-water, pharmaceutical, or other regulated service, obtain application-specific processing guidance and current supporting documentation before approval.
