UVINUL 4050 FF
UVINUL 4050 FF
UVINUL 4050 is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes.
Applications
UVINUL 4050 is recommended to be used in polystyrene, impact polystyrene, ABS, SAN, ASA, polypropylene, impact modified PP (TPO), EPDM, and in polyamides. Due to its low volatility, this product is unique for high temperature processes compared to other low molecular weight HALS
Features & Benefits
UVINUL 4050 provides excellent light stability for thick sections and films in the recommended substrates. A special benefit of using this product is the high light-stabilizing performance, particularly for styrenic polymers and PP to protect the surface. It has broad compatibility and can be easily dispersed. UVINUL 4050 can be used in plastic articles in contact with food.
Compared to UV absorbers, the low molecular weight HALS this product is not dependent on the polymer’s thickness. For this reason the use of UVINUL 4050 also provides good light stability in articles with a higher specific surface, e. g. films and tapes.
UVINUL 4050 can be used alone or combined with high molecular weight HALS, such as Chimassorb® or Uvinul HALS to achieve a synergistic performance.
