| Overview | Tetra-hydroxymethyl phosphor chloride The urea compact is also known as the polymer of tetramethylphosphine chloride and urea. It is formed by the reaction of hydroxymethyl in the molecular structure of tetramethylene phosphorus chloride (THPC) with urea. It is a colorless and transparent liquid, slightly acidic, and easy to biodegrade. |
| use | tetramethylphosphor chloride urea is mainly used as a flame retardant for textiles, especially for cotton textiles. it is still effective after repeated cleaning, has good soft hand feeling, little tear strength loss, and affects the original excellent properties of fabrics. |
