Polyurethane (PU) foaming additives

Combination of Omnistab UV 1 (a highly effective Benzamidine UV absorber which is widely used in polyurethane foam), Omnistab LS 123 or LS 292 as a liquid light stabilizer that have a synergistic effect with UV 1 combined with Omnistab AN 1135 which is a phenolic antioxidant that can prevent the formation of peroxides in the storage process of polyols and prevent scorching during the foaming process. These additives can be used for soft and hard foam systems.
