CAS: 144-55-8
Sodium bicarbonate (baking soda) is a chemical that it can be found everywhere, from the most simple things to heavy industry uses. George Wetzel ( 1791 ) discovered sodium bicarbonate. It became recognized by applying its purity derivatives in food, medicine and cleaning. Since then, and throughout the 19th century it solidified as a primary leavening agent for baking. The uses of sodium bicarbonate are not limited to the kitchen, it is also used in the pharmaceutical industry for medications against heartburn and exists as a personal care ingredient, toothpaste to deodorants. It is used in cleaning products, fire extinguishers and as an acid neutralizer for chemical processing. Another handy use for your baking soda, aside from washing your dishes, it is the old remedy for reversing a bad smell in shoes every so often in addition to refrigerators. It is a common material and can be bought for used in home or industries .

Applications in the Plastic & Rubber Industry
In Plastic and Rubber Industry, sodium bicarbonate is used especially a pH balancer and blowing agent. It decomposes when heated to produce carbon dioxide and gas that produces foam in plastics. Also, its buffering also maintains the optimal pH in production processes and thereby ensures product uniformity as well performance.
Other Industries Where Sodium Bicarbonate Applies
● Sodium bicarbonate versatility transcends wide-range of other sectors, including:
● Oil & Gas: Used in drilling fluids as a pH stabilizer and viscosity enhancer.
● Construction: Acts as an eco-friendly component in cement and concrete formulations.
● Personal Care: Commonly found in formulations for toothpaste and skin care products.
● Food & Nutrition: Closely related to baking (whitener), one of the most common leavening agents, which also is an acid neutralizer.
● Pharma: Employed in effervescent formulations and as a buffering agent in medicines.
● Agriculture: Applied in soil addition and pest suppression.
