Name and Features
Acrylic needle punched felt is one of the middle temperature resistance materials used to make filter bags, which has good hydrolytic stability.
Features
The continuous working temperature is 130-135 degrees, and the moment does not exceed 140 degrees.
Good acid and alkali resistance, PH value between 3-11.
The relative humidity is less than 30%, pay attention to oxidation.
Categories: Needle Punched Felts, Nonwoven Filter Fabric
Acrylic needle felt is a kind of fine fiber cloth using non-woven needle punching technology. The acrylic fibers are arranged in a staggered manner, the gaps are evenly distributed and large, the air permeability is good, and the chemical resistance is stable. It can not only filter normal temperature gas, but also filter medium temperature gas (150°C), it is an ideal choice for filtering acid, alkali and corrosive gases. Compared with polyester needle felt, the biggest feature of acrylic is that it has better hydrolysis resistance than polyester needle felt.
