Reactive flame retardant OP550 CAS184538-58-7 Product introduction: 0P550 is an efficient halogen-free reactive monomer mainly used in the production of polyether sponges. A small amount of addition can pass flame retardant standards such as FMVSS302, Cal117, BS5852, and UL-94. This flame retardant can be integrated into the structure of foam during the production process, and is less likely to migrate during foam aging, thereby enhancing the durability of flame retardancy and making it more suitable for the production of various flame retardant sponges. It can also be used for synthesizing phosphorus containing acrylic monomers, acrylic flame retardants, flame retardant coating adhesives, adhesives, elastomers, etc. Physical and chemical properties of OP550, including physical indicators, appearance, light yellow or colorless transparent liquid, hydroxyl value (mgKOH/g) (120-160), density (25C, Kg/m3) below 5, 1.260.05 phosphorus content (NT.%)>18.5 viscosity (25C, mpa. S), 200-25 acid value (mgKOH/g)<0.2 (almost undetectable). Reference formula (for reference only): Polyether 100OP5505 water 4.20 dichloromethane 1.260.05 silicone oil>1.1 stannous octoate 0.3A1<0.1A33<0.2TD180/20 (index) 110 density (kg/m). 24 notes: This formula can pass the FWVSS302 standard and Cal117 standard. The above are laboratory parameters for reference only. Actual values may vary depending on the foaming process conditions. Packaging and storage: 250kg iron drum packaging, stored in a cool, dry, and ventilated place.
