Each type of Filler masterbatch has some special properties to improve the end plastic product.
Plast Crystal.
A sodium‑sulphate based transparent filler masterbatch, engineered at particle level for clarity, strength and processability.
Clarity, engineered molecule by molecule.
Plast Crystal is a sodium‑sulphate (Na₂SO₄) based transparent filler masterbatch — a precision blend of ultra‑fine, inorganic transparent powder combined with virgin polyethylene carrier resin and a proprietary package of performance additives.
Every batch is proportioned to hit the exact physical and optical properties an end application demands, whether that's film clarity, sheet stiffness, or moulded‑part strength. The inorganic feedstock is imported from globally recognised sources, giving every lot the same consistent particle profile and processing behaviour, run after run.
The result is a functional filler that doesn't just dilute — it actively upgrades the resin system it's compounded into.
Built on four engineering pillars.
From raw‑material control to final resin compatibility, every attribute of Plast Crystal is tuned for predictable, repeatable performance on the production floor.
Manufactured for consistency.
Plast Crystal is produced on state‑of‑the‑art compounding lines, backed by a full‑fledged R&D and Quality Assurance function that screens every lot before release.
- Moisture and contamination‑free formulation
- Uniform particle size distribution
- Excellent dispersion within the polymer matrix
- Strong bonding and adhesion with the resin
- Low coefficient of friction
Drops into your existing resin line.
Plast Crystal is fully compatible with the entire polyolefin family — LDPE, LLDPE, HDPE and PP — as well as recycled polymer streams, without disrupting your line's output rate.
- Works across LDPE / LLDPE / HDPE / PP
- Blends cleanly with recycled polymers
- Improves volumetric output per kg of resin
- Holds quality parameters critical to the end application
Measurable gains in the finished part.
Compounding with Plast Crystal shifts the mechanical and optical profile of the end product in ways that are directly measurable on the test bench.
- Higher tensile and flexural strength
- Improved anti‑block characteristics
- Greater rigidity, stiffness and tear strength
- Cleaner surface finish and optimum transparency
- Better print receptivity
Performance that pays for itself.
As a partial substitute for virgin polymer resin, Plast Crystal is typically dosed at 10–20% depending on the application specification — reducing per‑kg resin cost without compromising the properties the part needs.
- 10–20% typical dosage range
- Non‑toxic and eco‑friendly composition
- Food‑grade compliant for packaging contact
An economic hedge against petroleum resin pricing.
Almost all plastic resin is derived from petroleum feedstock, so its price rises whenever oil and gas supply tightens. Bajaj Filler Masterbatches are available year‑round at a far steadier price curve — which means filled formulations stay commercially attractive even as base‑resin costs climb. The same virgin resins are open to every processor; what separates market leaders is the filler system used to engineer around that cost pressure.
Three decades of compounding expertise.
Bajaj began operations over thirty years ago in Nagpur, Maharashtra, and has grown into a group of specialised manufacturing entities — each focused on a distinct masterbatch category, all held to the same certified quality system.
ISO 9001:2015 Certified
Quality management certified by TÜV Nord, applied consistently across every production batch.
Dedicated R&D Wing
A full‑fledged research and development function continuously refines particle engineering and additive systems.
Four Manufacturing Entities
Bajaj Plast, Bajaj Polyblends, Bajaj Masterbatches and Bajaj Superpack operate under one quality umbrella.
Nationwide Reach
Regional enquiry desks across North, South, Central and Export zones keep supply consistent, nationwide.
What makes the particle chemistry work.
Ultra‑Fine Particle Size
Sub‑micron control of the Na₂SO₄ powder keeps optical clarity high even at working dosage.
Uniform Distribution
Consistent particle sizing across every lot avoids hot‑spots and gel formation during extrusion.
Excellent Dispersion
Engineered surface treatment lets the filler disperse evenly through the polymer melt.
Low Coefficient of Friction
Improves slip characteristics on film and sheet lines, reducing blocking and drag.
Strong Resin Bonding
Additive package promotes adhesion between the inorganic filler and the polymer matrix.
Moisture‑Free Formulation
Contamination and moisture‑controlled processing prevents voids and surface defects.
Every reason to make your product a quality product.
Five performance gains that show up directly on the finished part.

Food Contact Application
From raw powder to production‑ready pellet.
A controlled, four‑stage compounding process that keeps every batch within spec.
Raw Material Sourcing
Ultra‑fine, inorganic sodium‑sulphate (Na₂SO₄) transparent powder is imported from globally recognised feedstock sources for consistent quality lot after lot.
Compounding With Carrier Resin

Dispersion & Pelletizing
High‑shear processing on sophisticated compounding lines achieves uniform particle dispersion before the melt is pelletized into free‑flowing granules.
R&D & Quality Assurance
Every batch is screened for moisture content, particle size distribution and contamination before release, backed by a dedicated R&D and QA department.
