Poly-M-Xylylenadipamid (PAMXD6)



It is a crystalline polyamide produced by polycondensation of MXDA with adipic acid. Different from Nylon 6 and Nylon 66, Nylon-MXD6 is an aliphatic polyamide containing an aromatic ring in its main chain. Compared with Nylon 6 and Nylon 66, Nylon-MXD6 has the following favorable characteristics:

  • Greater strength and elastic modulus
  • High glass-transition temperature
  • Low water absorption and moisture permeability
  • Favorable crystallization speed and ease of molding and fabrication
  • Excellent gas-barrier properties
  • Ashby charts
