Exolit™ OP 540 (TP)
Exolit™ OP 540 (TP) is a non-halogenated, reactive flame retardant and a brownish-clear liquid of medium viscosity. The product based on oligomeric organophosphates has a functionality of approx. 2. Exolit™ OP 540 (TP) is primarily suited for production of flame-retarded polyurethane polymers, such as foams or elastomers. The product is distinguished by a high flame retardancy and a high ageing resistance in its flame retardant effect. In addition is shows a high migration stability due to its chemical incorporation into the polymer matrix.
Product Information
- Non-halogenated flame retardants with favorable environmental and health profile.
- Medium viscosity liquid for easy processing.
- Low migration and low fading of FR-performance due to chemical incorporation into the PU matrix.
- High phosphorus content allows excellent flame-retardant efficiency at low dosages.

Packaging
Exolit™ OP 540 (TP) is supplied in following packaging units:
1 kg sample bottles
50 kg PE open head drums (9 drums per pallet)
1.000 kg net in non-returnable 1.000 liter semi bulk containers
Storage
In the presence of moisture or water Exolit™ OP 540 (TP) hydrolyzes 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.
