ApplicationsExolit OP 560 is primarily designed for use in the production of special low fogging flexible polyurethane foams. The product is characterized by a high phosphorus content and high flame retardancy performance.
Exolit OP 560 is a reactive flame retardant, designed to be chemically reacted into the polymeric matrix. When properly incorporated into the foam, very low fogging values can be achieved which meet the most stringent emission standards for PU flexible foams in the automotive industry.
Exolit OP 560 should be added separately because it is only partially soluble in polyols with low hydroxyl numbers. As a reactive flame retardant it will hydrolyze slowly in the presence of water.
Packaging and HandlingDelivery form
Exolit OP 560 is supplied in following packaging units:
1 kg sample bottle
60 kg net drums (540 kg net pallets)
1,000 kg net non-returnable IBC
In the presence of water Exolit OP 560 hydrolyses slowly and should therefore be stored and handled with exclusion of moisture.
Minimum shelf life is 12 months from the date of shipping when stored according to the said conditions.
