TDL Series PP Meltblown Filtration Media for Plea | RFQ Sourcing Details

The TDL series is polypropylene meltblown filtration media intended for liquid filtration and conversion into products such as pleated filter cartridges and bag filters. The media is formed by melt processing, high-velocity air blowing, multilayer fiber lay-down, and, for the applicable grades, thermal calendering.

Customization is listed as available. Three product groups are offered. The classic micro-grade series includes TDL-1, TDL-2, TDL-3, TDL-5, TDL-7, and TDL-10, with stated mean pore sizes from 1 μm ±10% to 10 μm ±10%.

These grades have basis weights from 50 to 100 g/m², thickness ranges from 0.13 to 0.20 mm, and 500 m roll lengths. Listed widths are 10, 20, and 40 inches. The TDL-II micro-grade series covers item codes from TDL-05-II through TDL-10-II.

Depending on grade, stated mean pore-size ranges extend from 0.4–0.6 μm to 5.0–7.0 μm. Basis weights range from 45 to 110 g/m², listed thicknesses range from 0.14 to 0.26 mm, and roll lengths are 250 or 500 m. Width availability varies by grade between 10, 20, and 40 inches.

The uncalendered coarse-grade series includes TDL-13, TDL-15, TDL-18, TDL-20, and TDL-30. Their stated mean pore sizes run from 13 μm ±10% to 30 μm ±10%, with basis weights of 30–50 g/m². Rolls are 600 or 800 m long, and available width is listed as up to 240 cm.

The supplied information identifies applications including industrial process water and wastewater, food and beverage liquids, electronics-process reagents and ultrapure water, plating solutions, cutting fluids, oil purification, pharmaceutical intermediates, and biochemical solutions.

Suitability for any particular fluid or regulated process should nevertheless be confirmed against current technical and compliance documentation. The media is described as suitable for pleating, folding, ultrasonic welding, and edge sealing.

Procurement questions to confirm: Buyers should identify the exact TDL grade, required width, roll length, pore-size target, basis weight, thickness, and air-permeability requirement.

Also confirm whether the quoted pore value is a mean pore size or the required filtration rating, and request the applicable test method and lot acceptance limits.

Before ordering, verify chemical compatibility, operating temperature, flow rate, differential-pressure limits, contaminant loading, downstream cleanliness requirements, and suitability for the intended cartridge or bag-filter design.

Any required food- , drinking-water, pharmaceutical, environmental-management, or other market-specific documentation should be confirmed for the exact grade and shipment. Packaging configuration, inspection requirements, sample availability, production lead time, and warranty terms also require agreement.
