Optical Brightener Masterbatch: Enhancing Whiteness & Visual Brilliance
In the competitive world of plastic manufacturing, appearance plays a crucial role—especially for white, transparent, and light-colored products. That’s where Optical Brightener Masterbatch comes in: a powerful additive that visibly enhances brightness, whiteness, and glow by absorbing UV light and emitting visible blue-violet fluorescence.
It’s a smart solution for manufacturers looking to upgrade the aesthetic appeal of their plastic products without altering base polymers or increasing cost.
What is Optical Brightener Masterbatch?
Optical Brightener Masterbatch (OB Masterbatch) is a concentrated additive formulated using fluorescent whitening agents (FWAs) or optical brighteners dispersed in a compatible plastic carrier resin such as PE, PP, or universal base.
These brighteners absorb invisible ultraviolet (UV) light and re-emit it in the visible spectrum—giving plastic products a brighter, cleaner, and more vibrant appearance.
Technical Overview
Parameter | Specification |
Active Ingredient | OB-1, CBS-X, OB-2, or custom FWA blends |
Carrier Resin | PE, PP, universal |
Dosage Level | 0.01% – 0.1% |
Melting Point | 120°C – 160°C (varies by FWA) |
Appearance | Bright yellow or greenish powder/granule |
UV Stability | High |
Processing Methods | Injection molding, extrusion, blow molding |
How It Works
Optical brighteners are fluorescent compounds that absorb UV radiation (around 340–370 nm) and emit blue-violet light (around 420–470 nm). This emission:
- Masks yellow hues
- Increases contrast and perceived whiteness
- Gives plastics a glowing brilliance, especially under sunlight or UV lamps
The effect is optical, not chemical—so it doesn’t alter the plastic’s structure or degrade performance.
Conclusion
Optical Brightener Masterbatch is a small addition with a big visual impact. Whether you manufacture household goods, packaging, textiles, or industrial plastics, OB masterbatch helps you achieve a cleaner, fresher, and more professional finish—without changing your base materials or production flow.
It’s the ideal upgrade for brands focused on aesthetics, quality, and high-performance plastics.

Frequently Asked Questions
Our FAQ section provides clear answers to common questions about white masterbatches, from product features to application details. We aim to help you understand how our solutions can improve your plastic products. If you have further inquiries, our team is always ready to assist you.
What does an optical brightener do in plastics?
It makes plastics appear whiter, brighter, and more visually appealing.
Is it the same as a whitening pigment like TiO₂?
No—TiO₂ is a pigment; optical brighteners use fluorescence to enhance whiteness.
What’s the typical dosage of OB masterbatch?
As low as 0.01% to 0.1%, depending on the product and desired effect.
Will it work with colored products?
Yes, particularly effective in light colors like pale blue, green, pink, or grey.
Does it glow in the dark?
No—it fluoresces under UV or daylight, not in the absence of light.
Is it safe for food contact or hygiene products?
Yes—food-grade and non-toxic variants are available.
Does it affect mechanical strength?
No—it doesn’t interfere with plastic structure or processing.
Can it be combined with UV stabilizers?
Yes—though the formulation may be adjusted for balance.
Does it degrade over time?
Very slowly—its effect is long-lasting under normal usage.
What forms does it come in?
Usually in granules, powder, or masterbatch form in pelletized resin.
Can I use it in transparent plastic?
Yes—it improves clarity and reduces yellowness without clouding.
Will it affect printing or labeling?
No—it’s compatible with most surface treatments and coatings.
Is it visible under black light?
Yes—it emits a bluish glow under UV/black light, useful for security features.
Is it compatible with recycled plastic?
Yes—it can be used to brighten recycled or off-color batches.
What’s the shelf life?
Typically 12 to 24 months, if stored in a cool, dry place.
Can it reduce the use of TiO₂?
Yes—used together, it can reduce the amount of white pigment required.
Is it suitable for thin films?
Absolutely—ideal for film and sheet extrusion.
Will it change the smell or texture of plastic?
No—it’s neutral in both fragrance and touch.
Can it be customized?
Yes—custom OB formulations are available for specific polymers or effects.
Where can I buy high-quality OB masterbatch in India?
On trusted platforms like MasterbatchManufacturers.com or from verified suppliers.
