Micro Polypropylene needle felt

PP super-fine fiber filter material is a new type of filter material made of polypropylene special resin with the melt blown nonwoven technology. The fiber of the product with three-dimensional met structure decreases the filtering resistance and can contain more dust . The product is ideal to be used in initial, medium and high efficiency filter, self-air-cleaner , vacuum cleaner etc, due to its low resistance and high efficiency. The product can also be used for liquid filtration , oil stain disposal, water purification and other purpose.

Product Performance

The products is form hydrocarbons with innocuity, insipidity , white and light character.

The fiber distributes uniformly, softly and compactly , having the trait of high intensity, low resistance and high efficiency.

Acid and alkali resistant, with high melting point (157-174centidegree) and stable performance.

The material can be sued for air filteration and can filtrate undissolved impurities in organic solutions.

The material can be compounded with many other materials to reach the effect of gradient .
