Current:ENGLISH VERSION > TECHNICAL STRENGTH > Nylon 6/66 project
Project Name:  

  • Pa6-Project (Polytex tech,Polytex Design)
  • Main route:The caprolactam monomer is hydrolyzed at a high temperature to obtain aminocaproic acid, and then polymerized at a high temperature to obtain nylon 6.
  •  
    Project Description:  

  • Pa6 batch type (Single line:5TPD゛30TPD)
  • Pa6 continuous polymerization(Single line:15TPD゛120TPD)
  •  
  • Caprolactam melting system
  • Pre-Polycondensation system
  • Polycondensation system
  • Chip cutting system
  • Extraction
  • Nitrogen refining
  • Continuous drying
  • Packing system
