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,
  • occurs in a liquid form, giving the possibility of using at the stage of polymer synthesis,
  • 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.

Applications :

  • C.A.S.E. (Coatings, Adhesives, Sealants, Elastomers),
  • construction (roofing and roofing membranes, construction materials, window frames, PVC pipes),
  • plastics (production of synthetic rubber, SBR, technical films),
  •  textiles (coated fabrics, artificial leather),
  • electronics (cables and wires),
  • automotive (powder paints, gaskets, V-belts, tires, acoustic insulation).
