Taiwan's biggest Potassium Sulfate manufacturer,
collaborate the industry, hundred years sustainable development.

Since half century ago, Sesoda's stable pace of marketing managed to understand Taiwan's economic changes in development. Other than pure Soda Ash, followed domestic and international market needs, also began to produce product of Sodium Bicarbonate, Hydrochloric Acid, Ammonium bicarbonate powder and Potassium Sulfate...etc and use earthly materials to produce natural products.

Green Promise, Sustainable Development

Sustainable environment is our company's green promise. We followed“Achieve carbon reduction, build green homes, emphasize environmental education”in order to accomplish sustainable environmental development.


Product Application Field

Main products include: pure Soda Ash, Sodium Hydroxide, Sodium Bicarbonate, Ammonium bicarbonate powder, Potassium Sulfate, Hydrochloric Acid, Dicalcium Phosphate, flake Calcium chloride, liquid Calcium Chloride, etc.

Potassium Sulfate

Potassium Sulfate is a high-grade potassium fertilizer containing high Sulfur, high Potassium and low Chlorine. It is mainly used for grapes, citrus, flowers, tobacco and anaerobic crops. It is also used for cutting and cultivating delicate crops (such as greenhouse cultivation, hydroponic crops, etc.) considered as a premium fertilizer. Sesoda specializes in the production and sales of Potassium Sulfate (SOP) in the field of potash fertilizer. It is the largest manufacturer of Potassium Sulfate in Taiwan (and obtained ISO9002/CNS-12682 certification in 1996), with an annual production capacity of 140,000 tons, including around 100,000 tons powder Potassium Sulfate, and 40,000 tons of granular Potassium Sulfate; more than 98% of the output of Potassium Sulfate is exported to countries around the world.


Hydrochloric Acid (HCl)

Hydrochloric Acid, also known as Hydrogen Chloride (chemical formula HCl), is a strong acid used widely in industrial applications. Hydrochloric Acid is a colorless liquid, highly corrosive, and has a distinctively pungent smell. The 37% concentration of Hydrochloric Acid is a strongly volatile compound.


Liquid Calcium Chloride

In order to properly dispose of the by-product hydrochloric acid produced in the production of PotassiumSsulfate, Sesoda uses the reaction of hydrochloric acid and limestone to produce liquid Calcium Chloride, which not only meets the needs of customers with liquid Calcium Chloride for removing Fluoric acid, but also takes care of the environment and the earth


Soda Ash

Sodium carbonate (Na<sub>2</sub>CO<sub>3</sub>) has a molecular weight of 105.99, and its chemical purity is mostly above 99.5 (mass fraction). It is also called soda ash, but it is classified as salt, not alkali. Also known as soda or soda ash in international trade. It is an important inorganic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization and food processing. Sodium carbonate is a white powder that is easily soluble in water. The solution is alkaline (it can make the phenolphthalein solution light red). It can be decomposed at high temperature and will not be decomposed by heating.


Baking Soda

Sodium Bicarbonate (Baking Soda), commonly known as baking soda, is white powder or fine crystals, easily soluble in water, and weakly alkaline. It is an important raw material for manufacturing dyes


Flake Calcium Chloride

Flake Calcium Chloride is highly hygroscopic, easily soluble in water, and emits a lot of heat at the same time.


Ammonium Powder

Ammonium bicarbonate is a carbonate of ammonia. It is a white powder with a pungent smell similar to ammonia and has little solubility in water


Calcium Dihydrogen Phosphate (MCP)

Monocalcium Phosphate can be used as food additives and feed additives. Feed Standard Calcium Dihydrogen Phosphate is widely used as a Calcium Phosphate supplement for aquatic animals and livestock. Experiments have proved that the utilization of Phosphorus by aquatic animals and young livestock and poultry is the best Calcium Dihydrogen Phosphate among Calcium Phosphate salts, and the biological effect of Phosphorus is much higher than that of Calcium Hydrogen Phosphate.


Potassium Chloride

Potassium chloride is a commonly used fertilizer in agriculture (generally called "potash fertilizer"). In addition to being the main raw material for making potassium sulfate fertilizer, it can also be used in medicine, food processing, and other industrial applications


Solar Salt

Basic chemical raw materials for agriculture and industry, used in textile dyeing and finishing


Liquid Caustic Soda

Sodium hydroxide (45%), also known as caustic soda and caustic soda, is a highly corrosive strong alkali, usually in white flakes or particles, and can be dissolved in water to form an alkaline solution (liquid alkali)


Hydrogen Peroxide

Hydrogen peroxide is another kind of hydrogen oxide besides water. Generally stored in the form of 35% or 50% aqueous solution, the aqueous solution is commonly known as hydrogen peroxide. Hydrogen peroxide is highly oxidizing and weakly acidic


Calcium Sulfate

Calcium Sulfate is a common industrial chemical with a molecular weight of 136.14.The composition ratio is 29.5% for Calcium, 47% for Oxygen, and 23.5% for Sulfur.


Glauber's Salt

Glauber's salt, also known as Sodium Sulfate, also known as Na<sub>2</sub>SO<sub>4</sub>(crystal formed by the combination of Sodium Sulfate and water molecules).It is colorless and transparent, with glassy luster. It is called anhydrous Glauber's salt after loss of water. China's thenardite reserves rank first in the world. Glauber's salt mines are mainly distributed in Sichuan, Hubei, Tibet, Inner Mongolia and other places. Sesoda distributes the well-known Glauber's salt from the original mainland factory in Taiwan with stable quality


Barium Chloride

Barium Chloride is the Chloride of Barium, white crystals, also hygroscopic, and requires high storage conditions. Dongjiu is the agent of Qingdao Red Star Group for the sale of barium chloride in Taiwan


Sodium Sesquicarbonate

Sodium Sesquicarbonate is also known as Sodium Sesquicarbonate. It exists in the sediments of salt lakes in nature and is called trona or soda stone
