US - Tass needle felt can be continuously operated at a temperature of 204 ℃ (instantaneous temperature 250 ℃) 250 ℃ can withstand repeated temperature fluctuations of the moment, but also has excellent dimensional stability, at a temperature of 250 ℃ is only less than 1% of the thermal shrinkage, excellent high temperature stability. Good chemical resistance at low acid concentrations and it will not affect the majority of hydrocarbons, even a small amount of fluoride it does not corrode significantly. US-Tasman filter materials have been proven to be widely used in high temperature filtration applications, long-term use can maintain high strength, high wear resistance. Widely used in asphalt, cement, iron and steel, nonferrous metals, lime, dust, metallurgy, drying, crushed stone, plaster, plastic, carbon black, coke, shipbuilding, tobacco and other industries.
