Irgastab® PUR 68 by BASF is a BHT- & amine-free heat stabilizer blend designed for polyols. Exhibits good resistance to scorch, fogging, and textile staining. It offers outstanding resistance to foam discoloration after gas and light exposure. It allows dust free handling, automatic dosage and shortening of mixing time. Irgastab® PUR 68 is suitable for polyether- & polyester-based flexible foams and PUR flexible foams. It provides increased productivity by reducing weighing and metering to one single operation. It can also be added with additional antioxidants, co-stabilizers (phosphites) and light stabilizers (HALS, UVA). Recommended dosage level for slabstock polyol applications is 0.4-0.45% and for molding polyol grades is 0.05-0.1%.
