PP vs PE: Choose the Perfect Material for Your Liquid
| Material | Key Strengths | Best For… |
| Polypropylene (PP) | Excellent chemical resistance (acids, alkalis, solvents), heat-resistant (up to 90℃), and high tensile strength. | Industrial chemicals, oils, wastewater, and acidic/alkaline liquids. |
| Polyethylene (PE) | Ultra-pure, food-grade safe, resistant to oxidation and low temperatures (down to -70℃), gentle on sensitive liquids. | Food & beverage (juices, syrups, dairy), pharmaceuticals, and neutral/oxidizing liquids. |
Precision Filtration
| Filtration Precision | What It Traps | Ideal Applications | ||
| 1μm | Microscopic particles, colloids, fine sediment. | Pharmaceutical solutions, electronic cleaning fluids, precision coating liquids. | ||
| 3μm | Fine dust, small debris, suspended solids. | Cosmetics (lotions, serums), paint, and high-purity water. | ||
| 5μm | Medium particles, rust, pollen, algae. | Food processing (syrups, sauces), cooling water, and hydraulic oils. | ||
| 10μm | Larger sediment, dirt, organic matter. | Wastewater pre-filtration, industrial rinsing water, and general chemical filtration. | ||
| Custom (10-100μm) | Tailored to your specific impurity size. | Heavy-industry liquids, bulk processing, and unique liquid systems. |

Frequently Asked Questions (FAQ)
Q: What's the difference between PP and PE filter bags?
A: PP bags offer higher temperature resistance and are suitable for most chemical applications. PE bags provide better flexibility and are ideal for applications requiring superior seal integrity.
Q: How do I choose the right micron rating?
A: The micron rating depends on your application requirements. For fine filtration (removing small particles), choose lower micron ratings (1-10). For general filtration, higher ratings (25-100) are suitable. Our technical team can help you select the optimal rating.
Q: Are these filter bags reusable?
A: While some can be cleaned and reused, we recommend single-use for consistent filtration performance. Reusable options are available upon request.
