用于过滤器常用的主要过滤材料大致有以下几种：
The main filter materials commonly used in filters are as follows:
1、混合纤维素酯
1. Mixed cellulose esters
常用来制成圆形的单片平板滤膜，用于液体和气体的精过滤；
It is often used to make circular monolithic flat filter membrane for fine filtration of liquids and gases.
2、聚丙烯
2. Polypropylene
做成折叠式，常用于筒式过滤器，有较大的孔径，其具有亲水性，属粗过滤材料；
Made of folding type, often used in cylindrical filters, with larger aperture, hydrophilic, belonging to the coarse filter material;
3、聚偏二氟乙烯
3. Polyvinylidene Difluoride
属精过滤材料，耐热和耐化学稳定，蒸汽灭菌承受性良好，可制成亲水性滤膜，较广泛应用于制药工业无菌制剂用水及注射用水的过滤；
It is a fine filtration material with heat and chemical stability, good steam sterilization tolerance, and can be made into hydrophilic membrane. It is widely used in the filtration of sterile preparation water and injection water in pharmaceutical industry.
4、聚醚砜
4. PES
做成折叠式，常用于筒式过滤器，耐温耐水解性能好，亲水性材料，用于精度较高的溶液的精过滤；
It is made into folding type and is often used in cylindrical filter. It has good temperature resistance, hydrolysis resistance and hydrophilic material. It is used for fine filtration of solution with high precision.
5、尼龙
5. Nylon
做成折叠式，常用于筒式过滤器，亲水性材料，常用作液体的精过滤；
Made into folding type, often used in cylindrical filter, hydrophilic material, often used for liquid fine filtration;
6、聚四氟乙烯
6. Polytetrafluoroethylene
做成折叠式，常用于筒式过滤器，疏水性材料，其是使用相当广泛的一种材料，耐热耐化学稳定，常用于水、无机溶剂及空气的精过滤。
Made of foldable, often used in cylindrical filters, hydrophobic materials, it is a widely used material, heat-resistant and chemical stability, often used in water, inorganic solvents and air fine filtration.
另外，过滤材料按与水的关系分为亲水性（水可浸润的）和疏水性（水不浸润）两种。
In addition, filter materials can be divided into hydrophilic (water can be infiltrated) and hydrophobic (water does not infiltrate) according to the relationship with water.
亲水性的过滤材料主要应用在水或水/有机溶液混合的过滤和除菌过滤；疏水性过滤材料是通过水被截流或“引导”进入滤膜，主要应用在溶剂、酸、碱和化学品过滤，罐/设备呼吸器,工艺用气,发酵进气/排气过滤。
Hydrophilic filter materials are mainly used in water or water/organic solution mixtures for filtration and bactericidal filtration; hydrophobic filter materials are mainly used in solvent, acid, alkali and chemical filtration, tank/equipment respirator, process gas, fermentation intake/exhaust filtration through water interception or "guide" into the filter membrane.
