As the name implies, it is made of textile fiber thread wrapped tightly around a porous skeleton (polypropylene or stainless steel) according to a specific process. It is a kind of industrial commonly used filter consumables, can be made of 1-100 microns and other different precision, applied in different requirements of the industrial field. So what are the common materials?
One, PP polypropylene wire
PP polypropylene wire is a commonly used material in the wire wound filter element, often used in water treatment and pretreatment, it is made of polypropylene textile fibers, according to a specific process, closely wound on the porous skeleton, forming a honeycomb structure of the outer and inner dense filter element. Commonly used sizes range from 5 to 40 inches.
Features:
1. High filtration accuracy.
2. Large flow, small pressure difference, high pressure strength.
3. Large amount of pollution, long service life.
4. Non-toxic, tasteless, no secondary pollution.

Two, fat-free cotton
Fatless cotton is a deep filter element, the performance is better than PP polypropylene thread winding filter material, often used in liquid medicine, chemical solution and other low viscosity, low impurity mass filtration, its temperature and acid and alkali resistance performance is better than polypropylene thread, the commonly used size is 10-40 inches.
Features
1· Can withstand high filtration pressure.
2· Have good chemical compatibility.
3· The filter element can be made of a variety of materials to meet the needs of various liquid filtration.
4· The structure of the filter aperture is dense inside and thin outside, which has good deep filtration effect.
5. It can effectively remove the suspended solids and particles in the liquid, with small pressure drop and large fouling capacity.

Three, glass fiber
Glass fiber wire winding filter element is made of glass fiber according to the specific winding process, with different winding ways wound on the skeleton of different materials. The filter element adopts the structure of tight inside and loose outside, which has good deep filtration effect. Because glass fiber has strong temperature resistance and corrosion resistance, it is often used in sewage treatment, petrochemical filtration.
Features
Excellent chemical compatibility, suitable for filtration of strong acids, bases and organic solvents.
Low pressure difference, strong fouling capacity, long service life.
There are a variety of filter accuracy to choose from.
Progressive pore size changes provide ultra-high fouling capacity.
