Applications & Use Cases
  • Long-term UV light stabilization of polyolefin films, sheets, and fibers, where its high molecular weight resists extraction and volatilization during processing and outdoor service.
  • Protection of agricultural films, greenhouse covers, and geomembranes against photo-oxidative degradation over multi-season exposure.
  • Stabilization of polypropylene and HDPE molded parts, tapes, and woven raffia used in automotive, packaging, and industrial textile applications.
  • Light stabilization of wire and cable insulation and thick-section polyethylene articles requiring durability under sunlight.
  • Often used in synergistic blends with UV absorbers and antioxidants to extend the weatherability of pigmented and unpigmented polyolefin compounds.
