BASF (Ludwigshafen / Germany; www.basf.com) said its “Uvinul” 4050 FF monomeric hindered amine light stabiliser (HALS) has been registered for food contact in polymer applications in the EU and US. The product is suitable for appliances made from ABS, as well as packaging applications such as PP food crates.

“Consumers benefit from longer lasting end products, while plastic converters no longer risk any non-food contact cross-contamination,” said Klaus Koch, global product manager for light stabilisers at BASF. Uvinul 4050 FF, which replaces the chemically identical Uvinul 4050 H, generates less dust and has better flowability than powders, contributing towards improved health and safety during compounding or masterbatching processes, he added.

The product is approved within the EU for all types of polymer and food, within a specified migration limit. In the US, it is cleared for concentrations of up to 0.25% in PP and up to 0.5% in PS, styrene block copolymers and acrylonitrile copolymers.
