High-Quality Industrial Grade by AMAS Chemical
AMAS Chemical is a leading manufacturer and supplier of industrial chemicals in Iran, offering high-purity and reliable solutions for a variety of industries.
One of our flagship products is Caustic Soda (Sodium Hydroxide, NaOH), commonly known as soda lye or caustic soda flakes.
Caustic soda is a highly versatile chemical used in water treatment, pulp and paper, textiles, soaps and detergents, petrochemical processes, and chemical synthesis.
In addition to caustic soda, AMAS Chemical produces complementary chemicals such as Ferric Chloride (FeCl₃) and Poly Aluminum Chloride (PAC) for industrial and water treatment applications, offering integrated solutions for modern industrial needs.
Chemical Properties of Caustic Soda
Caustic soda is a strong alkaline inorganic compound with the chemical formula NaOH.
It is available in multiple forms, including flakes, pellets, and aqueous solutions.
Key Properties:
Chemical formula: NaOH
Molecular weight: 40.00 g/mol
Appearance: White flakes or pellets
Solubility: Highly soluble in water, releasing heat upon dissolution
pH: ~14 (for concentrated solution)
Density: 2.13 g/cm³ (solid)
Due to its strong alkalinity and high reactivity, caustic soda is widely used in industrial applications requiring pH adjustment, neutralization, saponification, and chemical reactions.

Production and Grades
AMAS Chemical manufactures high-purity caustic soda through the chlor-alkali process, ensuring minimal impurities and consistent quality.
Available Grades:
Industrial Grade: Suitable for pulp and paper, textiles, chemical industries, and water treatment.
Commercial Grade: Used in soap and detergent manufacturing.
Food Grade: Complies with international standards for food processing applications.
Packaging options include 25 kg and 50 kg bags or bulk jumbo bags, as well as custom packaging for large industrial consumers.
All shipments come with technical data sheets (TDS) and safety data sheets (SDS) to ensure proper handling.
Applications of Caustic Soda
Water Treatment
Caustic soda is widely used in municipal and industrial water treatment plants to control pH and alkalinity.
It neutralizes acidic water, prevents corrosion in pipelines, and supports chemical coagulation when used alongside coagulants like PAC and Ferric Chloride.
Key Benefits:
pH adjustment and stabilization
Corrosion control in pipelines
Enhanced coagulation efficiency
Cost-effective water treatment solutions
Pulp and Paper Industry
In the pulp and paper industry, caustic soda is essential for the kraft process, helping to break down wood chips into pulp and remove lignin.
It also aids in bleaching, pulping, and paper coating processes, ensuring higher quality products.
Advantages:
Efficient lignin removal
Increased pulp yield
Improved brightness and texture of paper
Consistent industrial performance
Soap, Detergents, and Chemicals
Caustic soda is a key ingredient in the production of soaps, detergents, and various chemical compounds.
It reacts with fats and oils in saponification to produce soap and glycerin, and is widely used in chemical synthesis for manufacturing sodium-based compounds.
Benefits:
High saponification efficiency
Consistent product quality
Reduced impurities in final products
Cost-effective and reliable
Petrochemical and Industrial Applications
In petrochemical industries, caustic soda is used for neutralization, refining, and cleaning processes.
It also plays a role in aluminum production, petroleum refining, and catalyst preparation, making it a vital industrial chemical.
Advantages:
Neutralizes acidic impurities
Improves yield in refining processes
Supports industrial cleaning and maintenance
Enhances chemical reaction efficiency

Food Industry Applications
Food-grade caustic soda is used for peeling fruits and vegetables, pH adjustment, and alkaline processing of cocoa, chocolate, and other foods.
It ensures food safety and quality when used according to
standards.
Complementary Chemicals by AMAS Chemical
AMAS Chemical offers a range of industrial chemicals that complement caustic soda in water treatment and industrial processes:
Ferric Chloride (FeCl₃)
A powerful coagulant used in wastewater treatment and industrial effluent management, removing suspended solids and organic matter efficiently.
Benefits:
Efficient coagulation
Reduces COD and BOD levels
Improves water clarity
Cost-effective and environmentally friendly
Poly Aluminum Chloride (PAC)
A high-performance coagulant for rapid floc formation and removal of turbidity and impurities in water treatment applications.
Advantages:
Works efficiently across a wide pH range
Produces less sludge
Improves water clarity
Reduces overall chemical consumption
Safety and Handling
Caustic soda is highly corrosive and requires proper handling.
Safety Measures:
Always wear gloves, goggles, and protective clothing
Store in a dry, well-ventilated area away from acids and moisture
Avoid contact with skin and eyes; in case of contact, rinse immediately with plenty of water
Follow all guidelines on the SDS for storage and transportation
