Acrylic needle felt is used by strong acrylic fiber nonwoven needle punched process staggered, superfine fiber cloth gap distribution, surface of hot, singeing treatment, the surface is smooth, not easy to be blocked by dust filter, the large gap, good air permeability, anti chemical stability, can not only filter the gas at room temperature. But in the high temperature gas filtration (150 DEG C) and is ideal for alkali corrosive gas filter material condition.
