Sodium Metasilicate Pentahydrate,Anhydrous .used in making high efficiency detergent and metal cleaner.Instead of STPP

Sodium Metasilicate Pentahydrate,

SiO2: 27-29%

Na2O: 28-30%

Water insoluble : 0.2%max.

Iron :200ppm

Whiteness : 80min

Bulk density : 0.80-0.97g/cc

PH of 1.0%solution : 12-13

Melting point : 72.2C
