Chemicals manufacturer, BASF has announced that its Uvinul4050 FF is the first monomeric hindered amine light stabilizer (HALS) to comply with Food-Contact Notification (FCN) 647 in the US and EU Directive 2002/72/EC. The additive is the first of its kind to get food contact approval in plastic applications.
The Uvinul 4050 FF, with food contact approvals and unique light-stabilizing characteristics, is an ideal additive for ABS polymers used in appliances. The additive can also be used for packaging purposes that need food contact approval, including bulk bags produced by polypropylene tapes and polypropylene food crates.
The Uvinul 4050 FF is an ideal substitute for the chemically similar Uvinul 4050 H and is delivered in an enhanced product form.
The Global Product Manager of Light Stabilizers at BASF, Klaus Koch, stated that the new, compact version of the Uvinul produces less dust and has enhanced flowability when compared to powders, resulting in enhanced occupational safety and health during the process of master batching or compounding.
The Uvinul 4050 FF has received approval for all kinds of food and polymer with a specific migration limit of 50 ppb within the European Union. The FDA has approved the product for concentrations of up to 0.5% in polystyrene and up to 0.25% in polypropylene in the United States.
