Reny is our proprietary molding compound, based on mainly polyamide MXD6 (PAMXD6) developed by Mitsubishi Gas Chemical Company, Inc.
Polyamide MXD6 is a crystalline thermoplastic polymer, manufactured from m-xylylene diamine (MXDA) and adipic acid. It exhibits higher mechanical strength/modulus and lower water absorption, compared to polyamide-6 and polyamide-66. In particular, when reinforced by glass fiber or mineral fillers, such compounds display the highest strength/modulus in engineering plastics, serving for various demand fields.

Chemical structure of Polyamide MXD6

Special features

  • Excellent mechanical strength modulus over a wide range of temperatures
  • Lower water absorption compared to commodity polyamides showing decrease in dimensional and mechanical strength change under water absorption condition
  • High heat distortion temperature, low thermal expansion coefficient, equivalent to metal alloys
  • Excellent chemical resistance against oils and organic solvents
  • Low mold shrinkage and low warpage , suitable for precise mold articles
  • Good surface finish even in high glass fiber content



Reny is suitable as an alternative to metal in many applications, including automobiles, electronics, electrical appliances, machinery, and construction.
