BASF Creates Monomeric HALS Light Stabilizer for Food Contact Applications in Plastics

The specific light-stabilizing properties of Uvinul 4050 FF, together with food contact approvals, make it the product of choice for all appliances made from ABS.

3/17/2011 --- BASF's Uvinul 4050 FF is claimed to be the first monomeric hindered amine light stabilizer (HALS) registered for food contact in polymer applications. The product is compliant with EU Directive 2002/72/EC as last amended in Regulation (EC) No. 975/2009 and with Food-Contact Notification (FCN) 647 in the US.
 
“Uvinul 4050 FF is the low-molecular-weight HALS with the broadest food contact approval in plastic applications. Consumers benefit from longer-lasting end products, while plastic converters no longer risk any non-food contact cross-contamination,” says Klaus Koch, Global Product Manager for Light Stabilizers at BASF.
 
The specific light-stabilizing properties of Uvinul 4050 FF, together with food contact approvals, make it the product of choice for all appliances made from ABS. It can also be used in packaging applications that require food contact approval, such as polypropylene (PP) food crates and bulk bags made of PP tapes.
 
Uvinul 4050 FF, which replaces the chemically identical Uvinul 4050 H, is supplied in an improved product form. “This new, more compact version generates considerably less dust and has better flowability than powders, making a significant contribution toward improved occupational health and safety during the compounding or masterbatching process,” explains Klaus Koch.
 
Within the EU, Uvinul 4050 FF is approved for all types of polymer and food, with a specific migration limit (SML) of 50 ppb. In the US, Uvinul 4050 FF is FDA cleared for concentrations of up to 0.25% in polypropylene and up to 0.5% in polystyrene. For styrene block copolymers and acrylonitrile copolymers, concentrations of up to 0.5% are approved.
