Acrylic chemical name is polyacrylonitrile, identifier number is DT. It is suitable for continuous temperature 125 C, instantaneous temperature not more than 140 C. Acrylic needle-punched felt filter material has good hydrolysis resistance, chemical corrosion resistance, but poor oxidation resistance. The needle-punched aramid felt and PPS filter materials with higher price can be replaced when the temperature range of normal dust removal operation is allowed.
