Polypropylene felt is a lightweight, flexible material that is great at absorbing liquids. Not only is it able to withstand higher solid loading than other materials, but it’s also temperature resistant and resistant to bleaches and most solvents.With all of its benefits, nonwoven polypropylene is also a low-cost material.Polypropylene needle punched felt PP non woven interlining fabric rolls has good flexibility, eco-freindly, permeability, waterproof, anti-pull, tear-resistant and dust prevention.

Polypropylene needle punched filter felt is made of polypropylene fiber and has the lowest temperature resistance. Because polypropylene fiber has more excellent acid resistance, alkalinity and lower softening point than polyester fiber, and the hydrolysis stability of polypropylene fiber is excellent, polypropylene needle punching Felt is generally used in the field of flue gas temperature below 100 ℃ and high acid and alkalinity or in the field of liquid and solid separation with large acidity and alkalinity and large moisture content. The polypropylene felt used for liquid-solid separation uses different specifications of polypropylene fiber, and uses ordinary or high-strength silk to make the reinforcing base fabric, which can be processed by hot rolling and singeing. It is used in conjunction with liquid filter separation equipment such as plate and frame filter press, vacuum suction filter, bag filter and centrifugal filter.
