In the plastics industry, the visual quality of products is as important as their functional properties. Yellowing, often caused by polymer degradation or impurities, can significantly diminish a product's appeal. This is where high-performance brightening agents like Optical Brightener SWN C.I. 140 become indispensable. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing top-tier solutions, offering this powerful additive to enhance the aesthetics of your plastic products.


Optical Brightener SWN, identified as C.I. 140, is a highly effective coumarin derivative designed to impart brilliant whiteness and vividness to plastic materials, particularly PVC. Its mechanism involves absorbing non-visible ultraviolet light and re-emitting it as visible blue light. This blue light counteracts the inherent yellowish tints in plastics, creating an illusion of enhanced brightness and cleanliness. The result is a more vibrant and visually appealing final product, crucial for market competitiveness.

Our Optical Brightener SWN C.I. 140 ensures superior whitening effects, making PVC pipes, profiles, films, and other molded products stand out.
