ApplicationsExolit OP 550 is primarily suited for the production of flame-retarded polyurethane foams. The product is distinguished by a high flame retardant efficiency and attains a high ageing resistance in its flame retardant effect as well as a high migration stability due to its chemical incorporation into the polymer matrix.
It is recommended to use an anti-scorching agent when processing Exolit OP 550. Potential anti-scorching agents include Hydroquinone, Lacton EG 472 or Irganox HP 3560.
Packaging and HandlingDelivery form
Exolit OP 550 is supplied in following packaging units:
1 kg sample bottles
50 kg PE open head drums (8 drums per pallet)
1.000 kg net in non-returnable 1.000 liter semi bulk containers
In the presence of moisture or water Exolit OP 550 hydrolyses slowly and should therefore be stored and handled in such a way to exclude any potential sources of moisture.
Minimum shelf life is 12 months from the date of shipping when stored according to the said conditions.
