I. Product Overview
As an important fine chemical product, fluorescent brighteners have broad application prospects in the industrial sector. At present, domestic and international research efforts are continuously dedicated to technological breakthroughs in this field, with the main directions focusing on the development of non-fading fluorescence, readily available raw materials, simplified synthesis processes, and environmental friendliness - practical and high-performance brightener solutions.
Jinan Tonex Chemical is pleased to recommend Fluorescent Brightener KCB, derived from the renowned German grade Telalux KCB, with CAS No. 5089-22-5 and purity ≥ 99%. The product appears as a bright yellow-green powder, non-toxic and odorless, insoluble in water. It exhibits excellent light fastness and heat resistance, does not react with blowing agents, crosslinking agents, or other additives, and shows no migration or extraction tendencies. Its maximum absorption wavelength is 370nm, delivering outstanding optical performance.
II. Scope of Application
Fluorescent Brightener KCB is widely applicable to the following fields:
Plastics Industry: Plastic films, compression molding materials, injection molding materials, etc.
Suitable Substrates: Polyolefins (PP/PE), PVC, expanded PVC, TPR, EVA, PU foams, synthetic rubber, etc.
Coatings Industry: Brightening of paints, natural lacquers, and other coating systems
Synthetic Fibers: Brightening treatment for synthetic fibers and plastic products
Notably, KCB exhibits exceptional brightening effects on foamed plastics, particularly EVA and PE foams. It also delivers significant color-enhancing effects on colored plastic products, effectively improving their visual appearance and market appeal.
III. Recommended Dosage & Application Guidelines
Recommended Addition Levels:
| Application Scenario | Recommended Dosage (per 100kg of material) |
|---|---|
| General Plastic Products | 5 ~ 50g (based on weight percentage of plastic raw material) |
| Foamed Plastics (EVA/PE foam) | Specifically effective; adjust according to actual whiteness requirements |
A Note from Jinan Tonex Chemical:
The above dosage ranges are for general reference only. The actual addition level should be adjusted based on raw material whiteness, target brightness requirements, and specific customer needs. For trial optimization, please feel free to contact our technical team for assistance.
