（DT）Acrylic dust filter bag
Experimental results show that, Acrylic have a good resistance to organic solution, oxidizing agent, organic acid & mineral acid at 125°C below. XXXX is not easy to hydrolyze, so, it is often replaced the materials of PE under the condition of low temperature, chemical corrosion, and moist. To meet the different requirement, we will deal with the acrylic needled felt by the various functional treatment ( Such as waterproofing and oil-proofing work, Dipping of PTFE, Coating, Laminating, etc.)
