China Metas Needle Felt Filter Bag

metas needle felt Filter bag
metas needle felt can be operated continuously at 204 °C and can withstand repeated temperature fluctuations of 250°C instantaneously, and has excellent dimensional stability, at 250 °C, the thermal shrinkage is less than 1% , which has excellent high temperature stability. Good chemical resistance at low concentrations of acids and bases and most hydrocarbons do not affect it, and even small amounts of fluoride do not significantly erode it. Matas filter material has been proven to be widely used in high temperature filtration field, long-term use can maintain high strength, high wear resistance. Widely used in asphalt, cement, steel, Non-ferrous metal, lime, dust, metallurgy, drying, crushed stone, gypsum, plastic, carbon black, coke, shipbuilding, tobacco and other industries.
