Acrylic needle felt filter bags also include acrylic film-coated needle felt filter bags. The acrylonitrile homopolymers they contain show good resistance to organic solvents, oxidants, inorganic and organic acids at temperatures below 125°C force. It should be noted that acrylonitrile homopolymer does not hydrolyze, so it is used to replace polyester at low temperature, chemical corrosion and humidity. The copolymer of acrylonitrile is not resistant to hydrolysis, so it cannot be used to replace the homopolymer in filtration applications. National Filter Environmental Protection is a professional manufacturer of acrylic needle-punched felt filter bags. The product models are diverse, and the materials used have been scientifically verified. It can play an effective role in filtration and has high filtration accuracy. In addition, acrylic needle-punched felt filter bags are of good price and high quality.
