2.532g/Cm3 Chemical Filler Soda Ash For Environmental Friendly Cas 497 19 8

Soda Ash Chemical Filler for Environmental Friendly Applications

Sodium carbonate.The chemical formula is Na2CO3, commonly known as soda ash, soda ash, alkali ash, disodium carbonate, and soda ash. It is usually a white powder and a strong electrolyte with a density of 2.532g/cm3 and a melting point of 851 ° C. It is easily soluble in water and glycerol, slightly soluble in anhydrous ethanol, and difficult to dissolve in propanol. It has salt like properties and belongs to inorganic salts. Moist air can absorb moisture and form lumps, some of which turn into sodium bicarbonate. The production methods of sodium carbonate include the combined alkali production method, ammonia alkali method, Lu Blan method, etc., and can also be refined by processing natural alkali. As an important inorganic chemical raw material, it is mainly used in the production of flat glass, glass products, and ceramic glazes. It is also widely used in daily washing, acid neutralization, and food processing. In terms of the environment, sodium carbonate is usually considered a relatively harmless substance to ecosystems. However, large-scale emissions may still affect the pH value and total alkalinity of water bodies, so appropriate management and regulation are needed during use and treatment.

‌Key Roles as a Filler‌

1. ‌Performance Enhancement in Polymers‌

   • ‌Plastics & Rubber‌: Improves dimensional stability, hardness, and wear resistance while reducing production costs37.
