Why Optical Brightener Masterbatch Is a Game Changer in Plastics

Fluorescent whitening agents. Recognized as optical brighteners, play a pivotal role in the industry. These additives are key in enhancing whiteness and brightness in plastic-based products. With KANDUI leading the way in maximizing the potential of this material.

Versatile Compounds

Compounds, whether in solid pellets, or liquid solutions. Or occasional solids, constructed from plastic compound CaCO3 (or similar fillers in powder form), plastic color. And additional additives. Through a meticulous process of melting, cooling, and granulating, these compounds formed. Reducing the reliance on primary plastics. Providing color to plastic products, and imparting functional properties. This diverse functionality categorizes these materials into three major types:

• Calcium Carbonate Filler
• Color
• Additive

Optical Brighteners: Illuminating Excellence

• Fluorescent Mechanism in Action

KANDUI’s Optical Brighteners take center stage in enhancing brightness, cleanliness. And whiteness in products. Operating on a fluorescent mechanism, these optical brighteners absorb light in the violet. And ultraviolet spectrums (340–370 nm) and re-emit it in the blue region (420–470 nm). Resulting in a bluish appearance that masks the effects of the color yellow.

• Precision in Dosages

To achieve these properties, specific brightener chemicals like diphenol vinyl-dibenzoxazol (C22H12N2O2) added to the base resin in small amounts, usually less than 5%. Recommended dosages, including OB1 (1%), OB2 (0.5%), and OB3 (0.25%), ensure optimal performance. These optical brighteners typically appear in the form of yellowish pellets.

Advantages of Optical Brighteners

• Outshining Alternatives

While manufacturers can achieve a bright. White look through alternative methods such as white or other plastic colors. The optical brightener stands out by ensuring visibility in both dark and light-deficient environments.

• KANDUI’s Superiority

Optical brighteners from KANDUI offer advanced properties, including:

• A distinctive blue-purple tint
• Enhanced radiance of colored articles
