CAI Performance Additives ST-LST5350

ST-LST5350 is a light stabilizer masterbatch with high loading of active substance based on hindered amine light stabilizer (HALS) chemistry. ST-LST5350 is available in pellet form, for general purpose use in automotive applications. The additive induces extremely low levels of unwanted VOCs. It is produced by a reactive process which differs from traditional reactive extrusion.

Product Highlights

ST-LST5350 is a  premium light stabilizing masterbatche for molded automotive components and other applications.

ST-LST5350 do not generate VOC or unintended odors, an advantage over more conventional light stabilizing solutions. Dust-free delivery makes them easy to feed while maintaining excellent dispersion.

ST-LST5350 is a high performing light stabilizer.

Benefits
  • Using polypropylene as a carrier, ST-LST5350 creates high functioning porous polymers to load and deliver additives with maximum efficiency and low VOC.
  • Does not create VOC and odors as some conventional compounded light stabilizers.
  • Dust-free delivery makes ST-LST5350 easy to feed while maintaining excellent dispersion.
  • High efficiency maximizing light stabilization while maintaining material properties.
