Product Details
First, the product introduction:
East China Chemical ECCH brand polyether refined adsorbent （synthetic magnesium silicate adsorbent, magnesium polysilicate, polyether purification agent） chemical name is synthetic magnesium silicate. Molecular formula: 2MgO.6SiO2.nH2O, CAS NO. 1343-88-0 Appearance is a white porous structure of spherical particles or powder, which belongs to amphoteric compound and exhibits excellent adsorption and decolorization properties as a polyether refined adsorbent. ; Adsorption of acid or alkali and potassium, sodium ions from organic chemicals, and aids in filtration. Adsorbs moisture from the air.
Polyether refined adsorbent （synthetic magnesium silicate adsorbent, magnesium polysilicate） is an international level product produced by our fine chemical company using 21st century advanced technology, equipment and perfect monitoring technology. The chemical properties and performance are comparable to those of the Japanese TomixAD-600NS grade and can be used as an import substitute.
