Characteristics of Acrylic Needle Felt Filter Cloth

The constant operating temperature ranges from 130 to 135 degrees, and the moment does not exceed 140 degrees.
Good acid and alkali resistance; PH ranges from 3 to 11.
When the relative humidity is less than 30%, pay attention to oxidation.
Categories include needle punched felts and nonwoven filter fabric.
Acrylic needle felt is a type of tiny fiber textile made with nonwoven needle punching technique.
The acrylic fibers are staggered, with equally distributed and big gaps, good air permeability, and durable chemical resistance.
It can filter gas at both normal and medium temperatures (150°C), making it an excellent choice for filtering acid, alkali, and corrosive gases.
The main advantage of acrylic needle felt over polyester needle felt is that it is more resistant to hydrolysis.
