Polyacrylonitrile fibers have good resistance for the organic solvents, oxidant, inorganic and organic acids and hydrolysis. Acrylic can be widely used in waste incinerators, bitumen, coal mills, and power plants for the dust collection at the low temperature, chemical corrosion and wet working occasions. According to different requirements, acrylic needle felt can receive different functional treatments, such as water and oil proof, PTFE dipping , coating, laminating and so on.
