Molecular weight:

400-500

Properties:

Colorless or pale yellow liquid

Usage:

As new reactive organic phosphorus flame retardant, THPO has ahigh phosphorus content（≥20.8）, containsan active hydroxymethyl,is excellent atHydrolysis resistance.Itcan be used for theproductionof polyether polyols as initiator, or as an additive to Polyether polyols then react with MDI.Polyether polyolsmade from THPOhaslow smoke, low toxicity, high carbon residue, and good compatibility, whichcouldbe used in polyurethane foam to increase the oxygen indexto30more, flameretardantrating to UL94- V-0 level and the combustion heat release rate is slow.THPOis a stable and long lastingflame retardant, it does not affect the mechanical properties of the material. so it can be used in rigid polyurethane foam of refrigerators, freezers, cold storage, building facades and so on.THPO containing an active methylol group, phosphorus-containing flame retardants may be used as synthetic intermediates.

Packaging and storage:

In250kg drum, sealed in plastic drums. Store in cool, dry and well ventilated area.
