Acrylic needle felt is the use of needle punched nonwoven process using acrylic strong fiber staggered, gap distribution of superfine fiber cloth surface by the treatment of hot rolling, such as singeing. its surface is smooth smooth, is not easy to be blocked by dust, this filter big gap. The air permeability is good, the anti chemical stability is strong. not only can filter the room temperature gas, but also filter the temperature gas (150°C) at the same time is the ideal choice of acid and alkali corrosive gas conditions filter material.
