Aminoether HALS

AddWorks® LXR™ 920

AddWorks LXR 920 is a halogen-free flame retardant for polyolefin films or fibers.The superior thermal stability results in low smokes and low odor generation during processing, even at high production temperatures.

AddWorks LXR 920 is based on Hostavin NOW - Clariant´s patented aminoether HALS technology - and further provides UV protection, excellent processability to the polymer and a superior chemical resistance to halogen - or sulfur - containing products.

  • Active at low concentration (2%) compared to other flame retardants.
  • High contribution to thermal stability of polyolefin.
  • Excellent processability in the polymer.
  • Processing possible even at high temperature (above 250°C).
  • Good organoleptic properties, no fume, no odour in the production.
The product does not require a hazard warning label according CLP regulation (Regulation (EC) No. 1272/2008, as amended).
