Production Process of PE Filter Cartridge
Screening UHMWPE powder and removing impurities.
Silicone oil is applied to both internal and external molds to ensure smooth surface after sintering.
High temperature (250-300℃) sintering for 5-6 hours to form a porous structure.
Natural cooling and demolding to avoid deformation.
Cut to standard length and conduct bubble uniformity test.
Sealed packaging to avoid contamination.
Advantages of PE Filter Cartridge
- Resistant to strong acid (sulfuric acid, hydrochloric acid), strong alkali (NaOH) and organic solvents (esters, ketones).
- No chemical adhesive to avoid secondary pollution.
- High porosity (50-60%), high flow rate per unit area.
- Smooth surface, impurities are not easy to adhere to, easy to backwash regeneration.
- The cost is lower than metal cartridge, long service life (can be repeated cleaning).
- Support non-standard customization, suitable for a variety of equipment.

Precautions
Frequently Asked Questions
What is the temperature limit for using PE filter cartridges?
For long-term usage, the temperature should be kept at or below 80℃. Although it can withstand short-term steam sterilization up to 130℃, higher temperatures can easily lead to structural deformation.
How can a PE filter cartridge be regenerated?
The recommended regeneration methods are utilizing a 0.6MPa compressed air blowback or performing acid/alkali immersion cleaning, depending on the nature of the filtered impurities.
What chemical resistances do PE filter cartridges offer?
PE filter cartridges are highly resistant to strong acids (such as sulfuric and hydrochloric acid), strong alkalis (like NaOH), and various organic solvents including esters and ketones. They are manufactured without chemical adhesives to prevent secondary contamination.
What should be done when filtering viscous liquids?
When dealing with high-viscosity materials, it is necessary to implement pre-filtration steps or add filter aids, such as diatomaceous earth, to ensure smooth flow and prevent premature clogging.
Are PE filter cartridges safe for food and pharmaceutical applications?
Yes, the UHMW-PE material used is GMP and FDA compliant. It is completely non-toxic, odorless, and suitable for pharmaceutical decolorization and drinking water/beverage terminal filtration.
