Applications and properties






 

Tiangang® HS-950 (Light Stabilizer 950) is a high-performance polymeric hindered amine light stabilizer(HALS), particularly suitable for polyolefins (PP, PE etc.), polyolefin copolymers, nylon, polyacetal and polyester, where it prevents photo-oxidation such as loss of mechanical strength and yellowing, improving weathering resistance. It can also be used in copolymers of polyolefins with EVA, PPO, in polyoxymethylene (POM), nylon (PA), polyurethane (PU), rigid and plasticized PVC (PVC) and PVC blends. It also provides good light stability in styrenics, rubber and adhesives.

As a polymeric high-MW HALS, Tiangang® HS-950 has excellent resin compatibility and extraction resistance, and suits systems requiring low volatility and low migration. It is particularly suited to films, tapes and fibers.Tiangang® HS-950 is a major upgrade to the widely used high-MW HALS Tiangang® HS-944, with a narrower molecular weight distribution and higher available nitrogen, and therefore better light stability.
