OB Optical Brightener Masterbatch is used for enhanced whiteness, brightness, and visual appeal are desired in plastic products. It is suitable for most plastic processing methods and works with a wide range of polymers.
Features & Advantages of Desiccant Masterbatch
-
Optical brightening
Built‑in high‑efficiency whitening agents that absorb invisible ultraviolet light , Significantly improves whiteness and brightness of plastic products, making appearance cleaner and more high-end. -
Carrier & dispersion
Customizable polymer carrier: PE, PP, PS, ABS, PET, EVA, or other base resins for full compatibility. Uniformly dispersed brightener crystals, no agglomeration, no fish eyes, no spots or streaks in film, sheet, or injection‑molded products. Low dust, free‑flowing pellets for clean feeding and automatic metering. -
Concentration & efficiency
High loading of active optical brightener for strong efficiency at low addition levels. Addition rate typically 0.2%–2.0% depending on required whiteness and base resin. Consistent performance from batch to batch for stable production. -
Improves product appearance
Enhances surface gloss, brightness, and texture for packaging films, shopping bags, fibers, household goods. Makes printed or laminated films look sharper and more attractive. -
Stabilizes product color over time
Reduces visible yellowing caused by thermal oxidation or UV exposure during processing and use. Maintains consistent whiteness during long‑term storage and outdoor application. -
Wide application versatility
Suitable for PE/PP films, BOPP, biodegradable plastics, injection molded parts, monofilament, woven bags, sheets, and thermoformed products. Performs well in both opaque and semi‑transparent applications.
Solve Yellowing & Dullness: OB Masterbatch Pain Points & Solutions
Painpoints |
Zinuo Solution |
|---|---|
Raw PE/PP/PET/EVA resin naturally shows a noticeable yellowish or off‑white tint. Finished products look dull, dark, and low‑grade, which directly reduces customer purchase intention and market competitiveness.
|
Our optical brightener masterbatch contains high‑efficiency fluorescent whitening agents that absorb ultraviolet light and release blue‑violet fluorescence, effectively neutralizing the inherent yellow tone of plastics, achieving a bright, clean, vivid white effect with enhanced visual brightness.
|
To improve whiteness, manufacturers have to increase the dosage of titanium dioxide (TiOâ‚‚), which greatly increases raw material cost, reduces product transparency, and increases haze, especially for thin films and transparent packaging.
|
Our OB masterbatch delivers excellent whitening effect at a low addition rate (0.2%–2.0%), allowing significant reduction in TiO₂ usage while maintaining high transparency and low haze, effectively lowering overall production cost.
|
During high‑temperature extrusion, film blowing, injection molding, and drawing, plastic materials are prone to thermal oxidation yellowing, resulting in color inconsistency between batches, unstable appearance, and high scrap rate.
|
Our OB masterbatch has excellent thermal stability (heat resistance up to 250–300°C), inhibits processing yellowing, ensures stable whiteness and color consistency batch after batch, and reduces defective products.
|
Using powder‑form brighteners leads to poor dispersion, agglomeration, fish eyes, black spots, streaks, and rough surfaces on films, woven bags, and injection‑molded parts, seriously damaging surface quality.
|
Our pellet‑type optical brightener masterbatch is specially dispersed and granulated, ensuring even distribution in the resin, no agglomeration, no gels, no spots, and maintaining a smooth, clean surface for finished products.
|
Plastic products gradually fade, turn yellow, or lose brightness under light exposure or long‑term storage, leading to customer complaints and after‑sales problems.
|
Our OB masterbatch provides long‑term anti‑yellowing and color retention performance, stabilizes whiteness and brightness under light and normal storage conditions, and maintains product appearance for a long time.
|
Low surface gloss and poor clarity lead to blurry printing patterns, poor lamination fastness, and unattractive packaging appearance, affecting product added value.
|
Our optical brightener masterbatch enhances surface gloss and optical clarity, making printing sharper, lamination more uniform, and overall packaging more high‑end and attractive.
|
Common brighteners have poor compatibility with slip masterbatch, antiblock masterbatch, color masterbatch, and filler masterbatch, causing migration, blooming, plate‑out, and reduced functional performance.
|
Our OB masterbatch has excellent compatibility with slip masterbatch, antiblock masterbatch, color and filler systems, no migration, no blooming, no negative impact on processing, ensuring stable overall performance.
