What is Sodium Ligno Sulphonate?
Sodium Ligno Sulphonate (also written as Sodium Lignosulphonate) is a water-soluble anionic polymer derived from lignin — a natural polymer found in wood and plant cell walls — through the sulphite pulping process. It appears as a brown to dark brown powder and is one of the most widely used and cost-effective construction chemical additives in the world.
Polychem Industries supplies Sodium Ligno Sulphonate to construction chemical manufacturers, concrete admixture producers, and industrial buyers across India and internationally. Its primary application is as a water-reducing plasticiser in cement and concrete formulations, but it finds use across multiple industries including animal feed, dust control, and agriculture.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Construction Grade | Brown Powder | 90%+ | Industrial | Concrete plasticiser, cement admixture, dust control |
| Industrial Grade | Brown Powder / Liquid | 85%+ | Industrial | Animal feed binder, agriculture, dispersant |
Applications & Uses
Concrete Plasticiser
The most common application — used as a water-reducing admixture in concrete. It allows reduction of water content by 10–15% while maintaining workability, resulting in stronger, more durable concrete at lower cost.
Cement & Dry Mix Mortars
Added to cement formulations, tile adhesives, grouts, and dry mix mortars to improve workability, extend open time, and reduce water demand without compromising strength.
Dust Control
Applied to unpaved roads, mining sites, and construction areas as a dust suppressant. It binds fine particles together and reduces airborne dust significantly.
Animal Feed Binder
Used as a binder in the production of animal feed pellets. It improves pellet durability and reduces fines during handling, transport, and storage.
Dispersant & Emulsifier
Used as a dispersant in dyes, pigments, pesticide formulations, and ceramics to improve dispersion of particles and stabilise suspensions.
Ceramics & Refractories
Used as a binder and plasticiser in the production of ceramic tiles, refractories, and other ceramic products to improve green strength and workability.
