Industrial lignin-based binder for granulation, briquetting, ceramics and construction materials.
Sodium Lignosulfonate Binder Grade is a water-soluble lignin-based polymer supplied as a yellow-brown powder for industrial powder systems that need better binding strength, dust reduction and formulation workability.
This grade contains sulfonic and carboxylic functional groups and performs as an organic binder, dispersant and processing aid in briquetting, granulation, ceramic, refractory and selected construction applications.
It is used where customers need particle cohesion, green strength, handling stability and smoother processing in mineral-based systems.
Key Performance Functions
Organic Binder
Improves cohesion of fine particles during briquetting, pelletizing, molding and granulation.
Dust Reduction
Helps reduce fine powder loss during production, handling, transport and storage.
Dispersing Support
Supports wetting and dispersion of inorganic particles in aqueous systems.
Process Lubrication
Improves moldability and extrusion performance in ceramic, refractory and mineral-based systems.

| Ceramics & Refractories | Binder and plasticizer for ceramic bodies, refractory mixes, tiles and mineral aggregates. | Improves moldability, lubrication, dimensional stability and dry strength. |
| Construction Materials | Organic binder and auxiliary dispersant for selected cementitious or mineral systems. | Supports workability, particle wetting and process consistency. |
Suggested Usage Guidance
| Application | Typical Starting Dosage / Use | Technical Note |
|---|---|---|
| Briquetting / pelletizing | 1.0% – 5.0% | Depends on powder type, particle size, moisture and target strength. |
| Ceramic / refractory mixtures | 0.1% – 1.0% | Adjust by slurry viscosity, molding method and dry strength target. |
| Construction / mineral binders | 0.2% – 1.0% | Lab testing is recommended before commercial formulation. |
| Pilot validation | Laboratory or pilot testing required | Performance depends on raw material type, drying conditions and final strength requirements. |
Dosage and application method should be verified by laboratory or pilot testing. Performance depends on raw materials, process conditions, temperature, moisture, mixing time and target technical results.
