PA66 is produced by polymerization Adipic Acid and HMDA. It has normally physical chemistry character as follow; strong wear resistance, chemical resistance, heat-cold resistance, impact resistance and adhesive property.
PA66 is possible to apply from general industrial property to use for food while contracting directly. Especially, PA66 has high melting point than PA6 and thus wide application range.

The process of N-66 manufacture

There are some elementary requirements to polymerize by using AH salt

Temperature(°C) Methanol concentration 15 25 35 45 55
100 0.407 0.481 0.560 0.841 1.25
90 - 3.56 4.76 6.55 10.1
80 - 10.7 14.0 19.9 24.4
70 - - 26.1 30.7 -
  • AH salt aqueous solution that is qualified to reduce or control the HMDA loss.
  • Law molecular weight compound polymerization under the condition of getting the equal molecular weight.
  • Polymerization of pre-polymer that has equal number average molecular weight, distribution of Normal MW, NH3 of No response of equal concentration, the final
    molecular weight as much as it want.
  • Polymer have to be prevent disassemble by minimizing the exposure to oxygen and high temperature.
  • Add the Delustrant in Polymer, way to disperse. Polymerization qualified the above conditions are possible by Batch or continuous polymerization. There are various
    reaction methods, for example; polymerize Molten Salt directly or polymerize the Molten HMDA and ADA.

Feature and Use

  • N-66 is applied to various uses by its feature.
    It has high elasticity, toughness and excellent light weight. So it can apply to Hosiery, sportswear, athletic wear, socks also EPR, Industrial yarn, apparel yarn.
  • Especially it has strong demand of industrial yarn for automobile, electronic EPR, tire cord and apparel yarn for parachute.
    We anticipate more functionality. Furthermore it has heat resistance, strong retention, young rate to tire cord application.
  • Also it has developed for auto-mobile, electric and electronic parts strengthening the advantage of heat resistance, low contractility and light weight. Recent PA 66 trend
    is that auto mobile components are being substituted for metal components.In case of fabric, there are technical developments of reinforced and high stiffness, which
    make rapid apply for fabric.
  • Development of exterior of auto mobile components, it is vital by complex technical (e.g. Polymer Alloy) development of composite material. In the electric parts,
    it has been demanded resistance to flame, high cycle grade. It is current market trend that there is an increasing demand from general purpose to special grade.
    Following the trend, it has been developed actively high impact resistance, Polymer Alloy, resistance to flame recently.

STABAMID R

  • It is a brand of global leader Rhodia that has stably supplied high quality product to engineering plastic market with best technical skill and know-how.
    STABAMIDR has produced high quality raw materials from Europe, Asia and South America factories that certified ISO 9001 and ISO 14001.
  • Application of STABAMIDR
