We are ISO9002 certified chemical manufacturer in china .We can supply
the following products with the best price:
1. sodium hypophosphite(102-103%)
Structural formula: NaH2PO2 .H2O
CAS No.: 7681-53-0 ,10039-56-2
Usage:Sodium Hypophosphite is mainly applied as reductant in non-electrical deposition of nickel (Nickel Chloride, buffers.) It builds complexes with the nickel in the bath, improving the fineness of the surface after treatment.It also be used to water treatment medical intermediate additive and etc.
2.THPS(75%)--Tetrakis(hydroxymethyl) phosphonium sulfate
Structural formula: [(CH2OH)4P]2SO4
CAS No.:55566-30-8
Usage: THPS is a biocide effective against micropest in industrial cooling systems, oil field operations, and paper-making industry. The advantage is it will soon degrade to a nontoxic substance immediately after use.
Also it can be applied to fabric coating, obviously improving flame retarding property.
3.THPC(75%)
Structural formula : [(CH2OH)4P] Cl
CAS No: 124-64-1
Usage:THPC is a flame retardant for textiles. Also a broad spectrum disinfectant and act as chemical intermiedates.
4. THPS-Urea(66%)
Structural formula : [(CH2OH)4P]2SO4.CH2N4
CAS Number: 63502-25-0
Usage: THPS-Urea is a flame retardant for textile. It can be applied as biocides in water treatment system too.
5.THPC-Urea(66%)
Structural formula : [(CH2OH)4P] Cl.CH2N4
CAS Number : 27104-30-9
Usage : THPC-Urea is a flame retardant for textiles.
