Exolit® OP 560

Highly effective reactive, non-halogenated phosphorus polyol

Edition Date :
May 30, 2018

Exolit® OP 560 is a flame retardant that can be used for flexible polyurethane foams. It is a medium-viscosity liquid and it is based on a non-halogenated phosphorus polyol. The product is a reactive flame retardant which can be chemically reacted into the polymeric matrix. Therefore, very low fogging values can be achieved which meet the most stringent emission standards for PU flexible foams in the automotive industry.

Watch how our Exolit® OP 560 can make the first trip to Mars safer.

  • Applications

    Exolit 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 Handling

    Delivery form
    Liquid

    Packaging
    Exolit OP 560 is supplied in following packaging units:
    1 kg sample bottle
    200 kg net drums (800 kg net pallets)
    1,000 kg net non-returnable IBC

    Storage
    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.
