General Chemistry

Caustic Soda Flakes 98% (Sodium Hydroxide)

Formula: NaOH GOST/CAS: CAS 1310-73-2 / ГОСТ 2263-79

Caustic Soda Flakes 98% (Sodium Hydroxide, Sodium Hydrate) is a high-purity, strong alkaline compound acting as a core raw material component across heavy, light, and processing industries. The product consists of odorless, white solid flakes exhibiting high hygroscopicity and excellent solubility in water, reacting with a significant release of heat. Due to its high concentration of the active substance (98%), this product is indispensable in chemical synthesis, neutralization of acidic mediums, industrial cleaning, and water treatment processes.

Applications

Chemical & Petrochemical Industry: Used for neutralizing acids and acid oxides, as a catalyst in chemical reactions, in plastics and synthetic fiber production, and for refining petroleum products and mineral oils.
Pulp & Paper Manufacturing: Utilized in the technological processes of sulfate pulp cooking, wood delignification, bleaching of paper and cardboard, as well as in waste paper recycling.
Soap & Detergent Production: Serves as a key alkaline base in manufacturing hard soaps, shampoos, washing powders, and professional technical detergents engineered for surface degreasing.
Textile Industry: Applied in the mercerization of cotton fabrics (alkali treatment to enhance strength and luster) and in fiber dyeing processes.
Water Treatment & Industrial Cleaning: Effectively used for regenerating ion exchange resins, adjusting water pH levels, and for Clean-in-Place (CIP) systems in food and beverage production facilities.

Key Advantages

High Chemical Activity: An active substance concentration of at least 98% guarantees maximum efficiency in saponification, neutralization, and hydrolysis reactions, reducing specific product consumption rates during production.
Stable Granulometric Composition: The flaked form minimizes the generation of caustic dust during handling, dosing, and transport, providing safer and more comfortable working conditions for personnel compared to powdered alternatives.
Excellent Solubility: Dissolves rapidly and completely in water, allowing for the swift preparation of working solutions of required concentrations without residue or sediment formation.
Versatility: Utilized across more than ten key industrial sectors, making it a globally standardized and irreplaceable chemical agent.

Storage & Transportation

  • Store in dry, covered, and well-ventilated warehouses, protected from moisture and direct sunlight, in tightly sealed original packaging.
  • Product is highly hygroscopic! Prevent packaging damage to avoid moisture absorption from the air and subsequent caking (clumping) of the flakes.
  • Keep separated from acids, oxidizers, ammonium compounds, and metals (such as aluminum, zinc, lead, and copper), as contact can trigger a violent reaction releasing flammable hydrogen gas.
  • Transportable by all modes of covered transport in strict compliance with dangerous goods regulations. The material is classified as Hazard Class 8 (corrosive substances). Personal Protective Equipment (PPE) including gloves, safety goggles, and respirators must be worn during handling.
