Caustic Soda Flakes, Packaging Type : Plastic Bags

Caustic soda flakes, also known as sodium hydroxide flakes, are widely used in various industries. The specifications of caustic soda flakes can vary based on the manufacturer and the intended application. However, general specifications typically include the following parameters:

### 1. **Chemical Composition**

- **Sodium Hydroxide (NaOH)**: Typically around 98-99%

- **Sodium Carbonate (Na2CO3)**: Typically less than 0.5%

- **Sodium Chloride (NaCl)**: Typically less than 0.05%

- **Iron (Fe)**: Typically less than 20 ppm

- **Heavy Metals (as Pb)**: Typically less than 10 ppm

- **Mercury (Hg)**: Typically less than 0.1 ppm

### 2. **Physical Properties**

- **Appearance**: White, semi-translucent flakes

- **Solubility**: Highly soluble in water, with the process being exothermic

- **Density**: Approximately 2.13 g/cm³

- **Melting Point**: Around 318 °C (604 °F)

- **Boiling Point**: Around 1,388 °C (2,530 °F)

### 3. **Packaging and Storage**

- Typically packaged in 25 kg bags, 50 kg bags, or bulk bags.

- Should be stored in a dry, well-ventilated area, away from acids and other incompatible materials.

- Containers should be tightly closed to avoid moisture absorption.

### 4. **Safety Information**

- **Hazard Statements**: Causes severe skin burns and eye damage; may be corrosive to metals.

- **Precautionary Statements**: Wear protective gloves, clothing, eye protection, and face protection. In case of contact, rinse immediately with plenty of water.

### 5. **Uses**

- **Chemical Manufacturing**: Used in the production of various chemicals.

- **Textile Industry**: For processing textiles.

- **Paper and Pulp Industry**: For pulping and bleaching processes.

- **Soap and Detergent Industry**: As a raw material.

- **Water Treatment**: For pH regulation and water purification.

These specifications can vary slightly depending on the specific requirements of the application and the supplier. Always refer to the supplier’s data sheet for precise information.
