In the complex landscape of polymer manufacturing, every component plays a crucial role in the final product's performance and market appeal. NINGBO INNO PHARMCHEM CO.,LTD. is proud to present Fluorescent Whitening Agent 369, also known as Optical Brightener KSB, a premium specialty chemical auxiliary essential for a wide array of polymer applications. This benzoxazole-based agent is not merely a whitener; it's a performance enhancer, designed to optimize the visual properties of polymeric materials.


Fluorescent Whitening Agent 369 delivers a powerful blue-white fluorescent light, effectively counteracting the inherent yellowing that can occur in many polymers. This leads to a perception of increased brightness and purity, which is particularly vital for products where visual aesthetics are paramount. Its application spans various polymer types, including polyolefins, PVC, EVA, and synthetic rubber, making it a versatile tool for manufacturers seeking to elevate their product lines. For those looking for a reliable fluorescent whitening agent manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. provides consistent quality.


Beyond its aesthetic contribution, the product’s robust chemical properties make it a valuable addition to polymer synthesis additives. It exhibits excellent heat and light resistance, ensuring that the enhanced brightness is stable and long-lasting, even under demanding processing conditions and environmental exposure. This high stability is a testament to its superior formulation, preventing degradation and maintaining performance over time. Such characteristics are critical for the longevity and perceived quality of end-products ranging from films and sheets to intricate injection-molded parts.


The high purity (≥99%) and low dosage requirement of Fluorescent Whitening Agent 369 contribute to its economic efficiency and ease of integration into existing manufacturing processes. Its good compatibility ensures that it disperses uniformly within the polymer matrix without causing processing issues or material defects. Whether you are aiming to enhance consumer plastics, industrial coatings, or specialized polymer compounds, this optical brightener KSB offers a reliable solution. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting your polymer manufacturing needs with high-quality chemical auxiliaries that drive innovation and success.
