Product Overview
Sodium Filler Masterbatch is a pre-dispersed, high-loading concentrate of ultrafine calcium carbonate (CaCO₃) in a polyolefin carrier resin — typically PP or HDPE. It is engineered to blend into base resins during plastic processing to reduce reliance on costly virgin polymer, cut production costs, and actually improve several physical properties of the finished product at the same time.
Unlike raw CaCO₃ powder, our masterbatch uses stearic acid-coated ultrafine particles (D50: 1.5–3.0 microns) that are fully pre-dispersed in a compatible carrier. When you add it to your hopper it mixes cleanly — no agglomeration, no die buildup, no surprise defects halfway through a production run.
CHEMICALLANE manufactures Sodium Filler Masterbatch at our Indian production facility under ISO 9001:2015 certified quality controls. Every batch is in-house tested for CaCO₃ loading, moisture, MFI, and whiteness before dispatch — so your line gets exactly what was quoted, every time.
Replace 20–40% virgin resin per run. Typical raw material savings of 15–30% without impacting product quality.
Stearic acid-coated ultrafine CaCO₃ (D50: 1.5–3 microns) — zero agglomeration, uniform melt mixing every run.
Factory-to-plant supply covering Surat, Rajkot, Delhi NCR, Mumbai, Hyderabad, Chennai and 100+ cities.
CoA, MSDS, TDS, and GST billing with every shipment for full compliance and audit readiness.

High mineral loading delivers maximum cost reduction per kg of finished product.
Guaranteed high whiteness index — no yellowing or discoloration in finished plastic products.
Ultra-low moisture prevents bubbling, streaking, or surface defects during extrusion.
At 25–35% dosage, processors typically cut raw material cost by 20–30% per kg of finished product compared to running 100% virgin resin.

Request DocumentsWhy Processors Switch
Every percentage point of filler loading is a percentage point of virgin resin you don't need to buy. Here's what the numbers look like in practice.
At 30–35% dosage, most processors cut virgin resin consumption by nearly a third — directly improving margin per tonne produced.
Improved melt stiffness and dimensional stability reduce cycle times on blown film and injection moulding lines.
High whiteness and opacity improve print quality and visual appeal of packaging products without added white pigment.
Stearic acid-coated ultrafine particles disperse completely in the melt — no die buildup, no unplanned machine downtime.

Industrial Use Cases
From flexible packaging to rigid industrial products, sodium filler masterbatch is a proven cost-saving input across 8+ major plastic processing sectors in India.
Improves opacity, stiffness, and printability of HDPE and LLDPE blown films for carry bags, packaging films, and agricultural mulch.
Reduces resin use in PP raffia tape and woven sack production while maintaining tensile strength and elongation performance.
Enhances dimensional stability, surface finish, and rigidity in moulded containers, household goods, and industrial components.
Increases stiffness and dimensional accuracy in HDPE and PP pipe extrusion — used in irrigation, plumbing, and conduit applications.
Improves opacity and rigidity in thermoformable PP and HDPE sheets for food trays, packaging boards, and stationery products.
Increases density and opacity in PP spunbond and meltblown non-wovens for hygiene, agricultural, and packaging applications.
Used in waterproofing membranes, vapour barriers, and construction packaging films requiring added opacity and stability.
Blended into recycled PP/HDPE streams to restore whiteness, opacity, and mechanical properties for second-life plastic products.
Usage Guide
Getting the dosage right is what determines how much you save without impacting product quality. These are industry-proven guidelines — our technical team will fine-tune the exact ratio based on your specific resin, machine, and product requirements.
A good starting point: begin at the lower end of the range and increase in 5% increments, monitoring tensile strength, elongation, and surface finish. Most lines settle into the 20–30% sweet spot.
