Primarily used in industries such as paper manufacturing, textiles, aluminum refining, soap production, and wastewater treatment. The requirements for impurities like heavy metals and chlorides are relatively lenient.
Used in the food processing industry, such as for bleaching, peeling, and cleaning.Complies with stricter hygiene and purity standards (often requires certifications like ISO or FDA approval).
Used for scientific research and high-precision experiments. High purity with minimal impurity content.
Caustic soda pearls appear as white spherical or semi-spherical granules with slightly perceptible color. Caustic soda pearls are water-soluble with an exothermic reaction, and they depict stability in normal conditions. Sodium hydroxide is a highly alkaline substance that dissociates completely in water into sodium and hydroxyl ions.
Chemical application and strengths：
• Caustic soda pearls or Sodium Hydroxide is one of the important inorganic materials for various industries all over the world. The major demand for caustic soda is evident in the paper industry for the pulping and bleaching process. Caustic soda is also a crucial raw material in aluminum production for dissolving bauxite ore.
• Caustic soda also finds many uses in the applications for degreasing and treatment of packaging in the food industry. The use of caustic soda is also prominent in chemical processing as a basic feedstock for various downstream products like plastics, solvents, etc.
•Caustic soda pearls also help in engendering the saponification of vegetable oils and fats required for manufacturing soaps. Caustic soda also finds applications in the textile industry for chemical processing of cotton. Most important of all, caustic soda is significantly important for the natural gas industry, where it helps in the production and processing of petroleum products.
• Caustic soda is also Important for elution stripping of gold that is adsorbed onto activated carbon. The mixture of caustic soda and cyanide interacts with carbon for extracting gold from the carbon. Special conditions of temperature , pH, and the flow rate of elution are highly important to the effectiveness of caustic soda In elution stripping.
• Caustic soda also finds small-scale applications such as paint stripping, chemical analysis, and aluminum etching. Furthermore, caustic soda is also used in various domestic products such as drain cleaners, oven cleaners, and other home-cleaning products.

From the nature of sodium hydroxide, sodium hydroxide has corrosive effects on fibers, skin, glass, ceramics, etc; Neutralize with acids to form salt and water; React with metal aluminum and zinc, non-metallic boron and silicon to release hydrogen; Disproportionation reaction with chlorine, bromine, iodine and other halogens; It can precipitate metal ions from aqueous solution into hydroxide; It can make the oil saponify and produce the corresponding sodium salt and alcohol of organic acid, which is also the principle of removing oil stains on the fabric. It can be seen that sodium hydroxide is widely used. The sector that uses sodium hydroxide most is the manufacturing of chemicals, followed by paper making, aluminum smelting, tungsten smelting, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts, the production of borax, chromate, manganate, phosphate, etc., also requires the use of a large amount of caustic soda. At the same time, sodium hydroxide is one of the important raw materials for producing polycarbonate, super absorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a large amount of sodium salt. In the overview of sodium hydroxide, we mentioned that sodium hydroxide is widely used in chemical industry, metallurgy, paper making, petroleum, textile, food and even cosmetics cream.
As a strong alkaline chemical raw material, sodium hydroxide can be used to produce borax, sodium cyanide, formic acid, oxalic acid, phenol, etc.
Sodium hydroxide saponified oil can be used to make soap and react with alkyl aromatic sulfonic acid to produce the active component of detergent.
The textile industry often uses sodium hydroxide solution to produce viscose fiber. Sodium hydroxide can also be used for fiber treatment and dyeing.
In sewage treatment plants, sodium hydroxide can reduce the hardness of water through neutralization reaction.
After being washed with sulfuric acid, petroleum products still contain some acidic substances. They must be washed with sodium hydroxide solution and then washed with water to get refined products
Sodium hydroxide can be used as a disinfectant. Prepare 1% or 2% caustic soda water solution, which can be used as a disinfectant for the food industry.
Industrial solid caustic soda shall be packed in iron drums or other closed containers with a wall thickness of 0 Above 5mm, pressure resistance above 0.5Pa, barrel lid must be sealed firmly, net weight of each barrel is 200kg, and flake alkali is 25kg. The package shall be clearly marked with “corrosive substances”. When edible liquid caustic soda is transported by tank car or storage tank, it must be cleaned after being used twice.
Store sodium hydroxide in a watertight container, place it in a clean and cool place, and isolate it from the workplace and taboos. The storage area shall have separate ventilation equipment. The packaging, loading and unloading of solid flake and granular caustic soda should be handled with care to prevent the package from being damaged to human body.
