What does melt-blown filter element mean in the filtration industry?

The melt-blown filter element, which is an extremely common element in the filtration industry is also one that has been around for a while. You can also call it PP cotton filter element. What is the use value of this filter element?


PP cotton filter element is also known as melt blown PP filtr element. It is a tubular filter made from polypropylene particles by heating, melting, spinning and traction. If the raw material is mainly composed of polypropylene it can be called PP Melt blown filter element.


The PP cotton filter element is made from fiber made of polypropylene resin. This resin is bonded to the fiber.


The filter element's layout is as follows: the outer fiber is thicker than the inner fiber, the inner fiber thinnest, the outer layer loose and the tightening of the mutation diameter of inner layer gradually tightens.


Common gradient deep filtration creates a three-dimensional filter residue function. It has the characteristics: high porosity and rejection, large dirt holding capability, and low pressure drop.


The PP cotton filter element can be used for large amounts of water purification. It also has exceptional chemical compatibility, and is suitable to filter strong acids and alkalis. High dirt holding capacity, low cost and long service life. The PP cotton filter element has a uniform pore size and high filtering power.


The PP cotton filter element has the following functions and characteristics:

Filters can effectively remove all types of particulate impurities from the liquid

It can have a multi-layered, deep structure that can store large amounts of pollution.

High filtration flow, low pressure difference


It does not contain chemical adhesives which makes it safer and more hygienic.

It is resistant to acids and alkalis as well as organic solvents and oils.

It combines surface, deep, coarse, and fine filtration. It has the characteristics of high flow, corrosion resistance and low cost. It blocks large particles like rust, sand and insect eggs in water.
