Solution of NAVI Titanium


NAVI Titanium applies controlled polymer processing to produce polypropylene forms with carefully defined permeability, surface characteristics, and dimensional profiles. Material behavior is governed by resin grade, thermal history, particle bonding, and internal passage geometry.



Gas Filtration Selection Quick Reference
Many overseas buyers' impression of sintered polyethylene sheet is limited to liquid precision filtration. In fact, its porous connected structure also has unique advantages in gas phase conditions - stable pressure drop, high dust retention rate, no fiber shedding, pulse blowback regeneration, and compared to sintered metal filter plates, its weight is only 1/5 and cost is 40% -70% lower. Its cost-effectiveness advantage is extremely obvious in non high temperature (PE grade ≤ 80 ℃, PP grade ≤ 90 ℃) gas-solid separation scenarios. We have summarized the common gas filtration models in the table below for reference.
| Working Condition Characteristics | Recommended Material Grade | Suggested Thickness | Key Selection Considerations |
| Room temperature, general dust, non-corrosive | Standard PE Grade | 5-10mm | Prioritize dust holding capacity and back-blow regeneration performance |
| Moisture-laden, oil-laden, sticky dust | PP Grade | 8-15mm | Smooth surface resists adhesion, compatible with online pulse cleaning |
| Gas temperature 70-90℃ | PP Grade | 10-20mm | Must confirm the maximum continuous working temperature limit |
| Acidic / alkaline / organic solvent gas | PVDF Grade | 5-15mm | Chemical compatibility comes first, medium composition required |
| Flammable and explosive dust environment | Anti-static Modified Grade | 10-20mm | Surface resistance controlled at 10⁶ ~ 10⁹ Ω |
| Pharma / food / electronic high cleanliness | Food & Pharma Grade or Electronic Grade | 3-10mm | Clean room packaging and leaching test reports required |
| High differential pressure (>0.6MPa) | With Reinforced Supporting Frame | 15-20mm | Must evaluate pressure differential and support structure |
Purchasing guide
Quality control (QC)
NAVI Titanium builds batch-level inspection and documentation directly into the delivery process, so every shipment can be verified against the technical requirements agreed at the quotation stage - covering material grades, dimensional results, coating or surface conditions, and specified performance data. These records also give buyers a practical reference for incoming inspection, production traceability, repeat orders and quality reviews. For customized orders, drawings, material specifications, inspection criteria and shipment records can all be bundled into the project documentation, providing procurement and engineering teams with a clearer basis for evaluating what they actually receive.

NAVI Titanium Core Performance Advantages
NAVI Titanium sintered polyethylene sheet is manufactured via high-temperature powder sintering without any adhesive, forming a uniform interconnected porous structure, outperforming both traditional solid plastic sheet and sintered metal sheet in targeted scenarios:
Compared with sintered titanium/stainless steel sheet, the material cost is 50%-70% lower, while the corrosion resistance in non-strong oxidizing acid/alkali scenarios is equivalent, delivering far higher cost performance for general industrial filtration use.
The monolithic sintered structure completely eliminates fiber shedding, no adhesive or impurity precipitation, perfectly matching high cleanliness requirements for food, pharmaceutical and new energy scenarios, avoiding product contamination risks.
Pore size and porosity are precisely controlled during the sintering process, with flow deviation across the entire sheet less than 8%, ensuring uniform fluid distribution without dead zones, which is ideal for fluidization, aeration and fluid distribution applications.
The lightweight plastic material is only 1/5 the weight of metal sintered sheet, can be easily cut, punched, welded and assembled on site, greatly reducing installation labor cost and equipment load.
Supports repeated backwashing, ultrasonic cleaning and chemical cleaning regeneration, service life is 3-8 times longer than disposable filter paper, filter cloth and melt-blown media, reducing long-term consumable cost by over 60%.
