Product Overview
Advantages of Water-Activated Self-Sealing Overflow-Stop Filter Cartridges Made of Sintered PE/PP Plastic:
1. Water-Activated Self-Sealing and Overflow Prevention Function：This filter cartridge is formed by sintering high-polymer polyethylene (PE) or polypropylene (PP). Its microporous structure automatically seals upon contact with water, effectively preventing liquid overflow. It is suitable for scenarios requiring precise liquid control (such as medical and laboratory applications). This feature is especially applicable in biopharmaceuticals, water treatment, and other fields, ensuring the safety and reliability of the filtration process.
2. Excellent Chemical Stability：PE/PP materials are resistant to strong acids, strong bases, and most organic solvents (such as esters, ketones, and ethers). Their chemical properties remain stable below 80°C, comparable to polytetrafluoroethylene (PTFE). The sintering process further enhances the corrosion resistance of the cartridges, making them suitable for harsh environments such as chemical and electroplating solutions.
3. High Precision and Uniform Pore Size：The pore size distribution of sintered filter cartridges is uniform, with filtration precision reaching up to 0.3 microns or more. They effectively capture fine particles while maintaining high flow rates. The consistent pore structure inside and outside facilitates backwashing and extends service life.
4. Mechanical Strength and Durability：PE/PP sintered filter cartridges have a compact structure and are lightweight, yet they can withstand high filtration pressures (for example, PE cartridges can withstand 4.5 bar at 80°C). They have good impact and wear resistance, making them difficult to damage and suitable for long-term use.
5. Environmental Friendliness and Cost-Effectiveness：These cartridges can be repeatedly cleaned and regenerated, reducing replacement frequency and lowering operational costs. The materials are non-toxic and odorless, complying with GMP, FDA, and other standards, making them suitable for food and pharmaceutical applications where safety is critical.
6. Temperature Adaptability：PE cartridges can withstand temperatures up to 80°C, while PA cartridges can withstand 120°C, meeting different operational requirements. They can also temporarily endure 130°C steam sterilization, making them suitable for high-temperature disinfection scenarios.
