1,PP super-thin fiber filtering media, 2,ISO9001:2000,CE,EN779 certification., 3,acid, alkali-resistant, high melting point. - details see: https://www.machineto.com/pp-super-thin-fiber-dust-air-filter-media-for-bags-10224737

Functions of products

1, as a kind of pure hydrocarbon, the products are harmless, smellless, light and white

2, even distribution, soft, dense, high strength, low resistance and high efficiency.

3, acid-resistant, alkali-resistant, high melting point (167-174)°c and stable functions.

4, good oil-immersing and heat-protecting preformance and good water-discharging ability.

5, can be used for air filtering and filtering of non-dissolvable impurities of organic liqid.

6, can be used to produce compound filtering media with other filtering media so as to achieve the result of ladder-type filtering.

This material is a new filtering media made of PP resin, the fiber of this productis 3-D net structure, which leads to low filtering resistance, increased dust-holdig capacity and high efficiency. the products are ideal for initial, medium and high efficiency filters, air self-purifying devices and cleaners, the products can also be used for oil dirt treatment and water purification.

The most important that we have our own test devices: Laser dust particle counter and Weight-counting test, high efficiency filter tester, our technical have international leading level with very high and stability quality.
