MX Nylon

Nylon-MXD6 is a generic name given to a wide range of polyamides produced from m-xylenediamine (MXDA) by Mitsubishi Gas Chemical Co., Ind. The polymerization technology of this resin has been licensed to MAP by Mitsubishi Gas Chemical Company (MGC). MGC pioneered the sophisticated technology behind the process that separated high purity m-xylene and manufactured MXDA used as the backbone of this unique polymer. MGC has a long history in the development of a protected MX Nylon process and patented MX Nylon grades.

MX Nylon is a crystalline polyamide produced by the polycondensation of MXDA and 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, MX Nylon has the following favorable characteristics:

  • Excellent gas barrier properties against oxygen, carbon dioxide and other gasses – the best gas barrier property of all nylon resins, better gas barrier over EVOH in a humid atmosphere.
  • Superior recyclability – easy to recycle without any gel formulation or decomposition.
  • Good processability – easy to stretch and/or thermoform because of the moderate crystallization speed and higher glass transition temperature.
  • Good retortability – keeps excellent gas barrier property even after retorting or boiling treatment.
  • Higher tensile and flexural strength and modulus

These features lead to greatly varied applications for MX Nylon as a packaging and molding material, and in the production of monofilaments.

MX Nylon shows an excellent gas-barrier quality against oxygen and carbon dioxide. Under certain conditions, its gas-barrier quality exceeds that of copolymerization resins such as ethylene vinyl alcohol (EVOH), vinylidene chloride (PVDC), and acrylonitrile (PAN).

The molding specifications of MX Nylon match well with the criteria for molding other materials. This means you can use MX Nylon in combination with polyethylene terephthalate (PET), polypropylene (PP), or polyethylene (PE) to achieve co-injection molding and co-extrusion molding to produce laminated containers, bottles, and packaging sheets.
