APSM

What is APSM ?

APSM(CSDS)—Active Poly Sodium Metasilicate (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$ 500 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 the formula.
