Filler Masterbatch

Na₂SO₄ · Sodium Sulphate · Imported Fine Powder

We are one of India's largest suppliers of Na₂SO₄ Filler Masterbatch — made from ultra-fine sodium sulphate powder not yet available domestically in India. Our SF SUPER and SF ULTRAFINE brands are specially designed for PE film manufacturers where transparency is critical.

Unlike conventional fillers that cloud films at high loadings, our SF Masterbatch maintains film transparency even at loading ratios up to 70% — delivering exceptional cost reduction without compromising product quality.

✓Maintains transparency even at 70% loading — unique advantage
✓Made from ultra-fine Na₂SO₄ powder — not available in India
✓Imported grade — superior to domestically available alternatives
✓Widely used in PE films, carry bags, packaging films
✓Significant cost reduction per kg of finished product
✓Pan India supply — fast dispatch from Kolkata

🔬 Why SF Masterbatch is Different

The ultra-fine Na₂SO₄ particle size is the key — conventional sodium fillers use coarser powder that scatters light and reduces transparency. Our imported fine powder grade does not. This is why our product is uniquely trusted by PE film producers across India who need both cost efficiency and clarity.
