Nonwoven Polyester/PET Filter and Raw Material For Industrial Dust Collection System in Cement Industry

PET Needle Felt is made of PET staple fiber by needling process. The surface of this product is neat and smooth after certain finish treatment such as heat-setting, singeing, calendaring or coating. It has the advantages of large porosity, high air-permeability, long working life, low price etc. It is an ideal filter medium under normal temperature in areas of solid-liquid separation and gas-solid separation and widely used in steel industry, non-ferrous metal, chemistry industry, cement and foodstuff etc.

1 Feathers:

1)Large Porosity
2)Good Air Permeability
3)Easy Seperation
4)Stable Chemical Property
5)Long Working Life

2 Appliction:

It Can Not Only Filtrate Normal Temperature Gas,Water,Oil But Also Corrosion Gas With Acidity,Alkalinity.
