APSM/CSDS—Active Poly Sodium Metasilicate or Complex Disodium Silicate, is specially designed to replace STPP in washing powder industry. It is considered as the ideal replacement for STPP and widely accepted by the markets due to Huge Saving in Costs, Friendly to Environment, and Nice Performance in Function.
CAS No. 1344-09-8/ 497-19-8
Molecular Formula: mNa2O.nSiO2.xH2O
HS Code: 3824999999
Why APSM ?
*Huge Cost-Saving
About US$ 400 per MT cheaper than STPP. One Million US$ can be saved if 2500MT STPP replaced by APSM per year .
*Eco Friendly:
It is much more friendly to environment as a phosphate-free detergent auxiliary. STPP already prohibited to use in many countries. More and more markets will gradually give up STPP in the near future for our nice planet.
*Nice Performance in Function:
*APSM can be fully and quickly dissolved in water.
*In terms of Ca2+/Mg2+ exchanging capacity, it is almost the same level with STPP(see below specification).
*APSM is highly compatible with any kinds of surfactant(especially the nonionic surfactant), itself has the capacity of detergency as well.
-How to Use
At initial stage, recommend dosage is 70% STPP replaced by APSM (1000KG STPP you used before, now 700KG APSM+300KGSTPP).
95% or fully replace STPP gradually in your formula,.
