Features Of Songwon SABO STAB UV 40 Polymeric Hindered Amine Light Stabilizer

  1. High molecular weight polymeric structure ensures excellent melt stability and minimal volatility during high-temperature processing.

  2. Superior long-term light stabilization performance due to regenerative hindered amine mechanism (HALS).

  3. Outstanding compatibility with polyolefins, including PP and HDPE, without blooming or plate-out issues.

  4. Low extractability in aggressive media, enhancing durability in outdoor and automotive applications.

  5. Non-basic HALS chemistry minimizes adverse interactions with acid-sensitive additives such as certain flame retardants or pigments.

Typical Applications Of Songwon SABO STAB UV 40 Polymeric Hindered Amine Light Stabilizer

  1. Automotive exterior components (e.g., bumpers, trim, grilles).

  2. Outdoor building & construction materials (e.g., siding, decking, roofing membranes).

  3. Agricultural films and greenhouse covers requiring extended UV resistance.

  4. Geotextiles and geomembranes exposed to intense solar radiation.

  5. Consumer durable goods (e.g., garden furniture, storage containers, playground equipment).
