Hydrolytic stable processing stabilizer for coatings and plastic materials

AddWorks® LXR 568 MP

AddWorks LXR 568 MP is a highly efficient phosphorous based processing stabilizer solution, which reduces the thermo-oxidative degradation of polymers and the development of undesired color (yellowing). AddWorks LXR 568 MP shows enhanced hydrolytic stability, a high thermal stability and high solubility in polymeric materials. It has a broad compatibility in coating polymers.
  • Low dosage
  • High performance in color and melt flow retention during conversion process
  • Wide application window allowing high processing temperatures
  • Low softening temperature providing early stage protection in extrusion processes
  • Significant contribution to dyne level retention
  • High solubility in polymer virtually no haze or blooming
  • Good hydrolytic stability
  • High contribution to thermal stability of filled polyolefin and engineering plastic compounds
  • Higher contribution to polypropylene clarity compared to other processing stabilizers
  • Low plate out, low die buildup
  • Preventing formation of char and specks
