Product Overview
Polymer polyethylene/polypropylene (PE/PP) plastic powder sintered filter tubes show significant advantages in the field of industrial filtration with their unique material and process design, and the core advantages are as follows:
🧪 1. Excellent chemical stability
Broad-spectrum corrosion resistance
Strong acid and alkali media with pH 2–12 resistance, excellent compatibility with esters, ketones, ethers and other organic solvents, better than metal filters
Food and pharmaceutical grade safety
The material complies with GMP/FDA standards, no binder added, non-toxic and odorless, suitable for sterile liquid, drinking water purification and food processing
⚙️ 2. High-performance physical characteristics
Precision filtration capabilities
The labyrinthine microporous structure (pore size 0.2–100μm) achieves efficient interception, with a maximum accuracy of 0.2μm (liquid-solid) and 0.3μm (gas-solid) to ensure fluid cleanliness
Strong mechanical properties
The compressive strength is ≥4MPa, the flexural strength is ≥5MPa, and the impact strength is up to 4.5MPa, which is not easy to damage during transportation and installation
Pro/hydrophobic can be customized
It supports hydrophilic or hydrophobic design, and the hydrophobic type can be used as a check valve when it encounters water, and the hydrophilic type increases the liquid filtration flow rate
