Properties and applications

Product application advantages:

  • eliminates the effect of yellowing of materials during processing,
  • enhances the colour stability of polymeric materials containing pigments,
  • provides transparency in non-pigmented materials,
  • prevents degradation processes during thermal processes,
  • acts synergistically with amine and phenolic stabilizers,
  • one of the components of "mixed metals" mixtures in PVC processing,
  •  non-staining properties,
  • no negative effect on the mechanical properties of the material.
