BX FR OP550

Introduction

BX FR OP550 is an organic halogen-free phosphorus flame retardant, mainly used in flexible Pu form, PU coatings, TPU adhesives, PU elastomers, PU casting, polyurethane foaming, and other systems. This product contains hydroxyl functional groups and is a reactive flame retardant, ensuring that it will not migrate or precipitate after addition. Analog to clariant Exolit OP 550/560.

Features:

1. Halogen-free and environmentally friendly;
2. Low VOC:
3. Migration resistance:
4. No precipitation:
5. High flame retardant efficiency and anti-aging performance;
6. High phosphorus content and excellent hydrolysis stability:

Specifications:

Appearance: slightly yellow, clear liquid
Phosphorus content (%) 17
Hydroxyl value: 120-140
Acid value: <0.5
Water content: 0.1%

Dosage

BX FR OP55 organophosphorus flame retardant must be added to the isocyanate component to react with the isocyanate monomer to work.

1. In the production of flame-retardant polyurethane foam, dosage is 5-15%;
2. In the polyurethane system, add 5-15%:
3. In other systems, add 8-12%:
