Sodium Alginate is a highly versatile natural polymer with applications extending far beyond food and textiles into various industrial processes. For procurement managers and R&D scientists in these sectors, understanding the specific technical requirements and sourcing high-quality Sodium Alginate is crucial for process optimization and product quality. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of Sodium Alginate grades suitable for diverse industrial needs.

Key Specifications of Industrial Grade Sodium Alginate

When sourcing Sodium Alginate for industrial applications, several key specifications dictate its suitability:

  • Viscosity: This is arguably the most critical parameter. Sodium Alginate's viscosity is typically measured in centipoise (cps) at a specific concentration (e.g., 1% solution). Industrial processes such as drilling fluids, ceramic manufacturing, or adhesives may require specific viscosity ranges. A higher viscosity generally means a greater thickening effect.
  • Purity: While food-grade Sodium Alginate has stringent purity requirements, industrial grades may vary. It's essential to know the required purity level for your application to avoid unwanted side reactions or contaminants affecting your process.
  • Particle Size (Mesh): The fineness of the powder (e.g., 30-120 mesh) influences its dissolution rate. Finer particles dissolve faster but can be prone to clumping if not dispersed properly. Coarser particles might require longer mixing times.
  • pH Value: Sodium Alginate solutions typically have a neutral to slightly alkaline pH, generally between 6.0 and 8.0. This can be an important factor in formulations sensitive to pH.
  • Moisture Content: A low moisture content is desirable for shelf stability and to ensure accurate weighing for formulations.
  • Ash Content: This indicates the level of inorganic impurities present. Lower ash content is generally preferred for applications requiring higher purity.

Industrial Application Examples

  • Oilfield Chemicals: Used in drilling fluids as a viscosifier and fluid loss reducer.
  • Ceramics: Acts as a binder and suspending agent in glazes and slips.
  • Adhesives: Can be used in water-based adhesives due to its thickening properties.
  • Paper Manufacturing: As a sizing agent to improve paper strength and printability.
