The aesthetic appeal and longevity of plastic products are crucial for market success. To achieve vibrant and lasting whiteness, specialty plastic additives play a vital role. NINGBO INNO PHARMCHEM CO.,LTD. proudly presents Optical Brightener ER-I, also known as Fluorescent Whitening Agent 199, a high-performance solution that significantly enhances plastics color enhancement and provides excellent UV stability.


Optical Brightener ER-I for plastics is a yellow-green crystalline powder that converts UV light into visible blue light, counteracting the natural yellowing that can occur in polymers. This unique mechanism results in a brighter, crisper, and more visually appealing product. As a leading plastic whitening agent supplier, NINGBO INNO PHARMCHEM CO.,LTD. ensures that ER-I offers superior purity (>98%) and exceptional migration resistance, critical for maintaining consistent appearance over time, even under light exposure.


Our Fluorescent Whitening Agent 199 offers excellent light and heat resistance, making it suitable for various plastic processing methods including extrusion, injection molding, and compounding. It's particularly effective for polyester fiber printing & dyeing applications within plastics, delivering high fluorescence intensity with a low addition rate. This efficiency means a more cost-effective solution for manufacturers aiming to improve product quality and consumer perception.
