Optical Brightener Expands Application Scope with Performance Upgrade
Release time:
2026-01-30
Optical brighteners, also known as fluorescent whitening agents, are chemical additives that can improve the whiteness and brightness of materials. They absorb ultraviolet light and re-emit it as visible blue light, offsetting the yellowish tone of materials and achieving a whitening effect. In recent years, with the continuous upgrading of market demand for product appearance, optical brighteners have achieved significant progress in performance upgrading.
The upgraded optical brighteners have enhanced whitening efficiency, and can achieve obvious whitening effect with a small addition amount, while having good compatibility with various base materials such as plastics, textiles, paper and detergents. At the same time, the product stability has been significantly improved, which can adapt to high-temperature processing environments such as plastic extrusion and textile printing and dyeing, and is not easy to decompose or fade, ensuring the durability of the whitening effect. In addition, the optimized optical brighteners have better environmental performance, complying with relevant environmental protection standards and reducing potential impact on the environment and human health.
In terms of application, optical brighteners are widely used in plastic products, textile fabrics, paper making, detergents and other fields. In the plastic industry, they are used to whiten PVC, PP and other plastic products; in the textile industry, they can improve the whiteness of cotton, polyester and other fabrics; in the paper industry, they can make paper products more white and bright. The continuous performance upgrade of optical brighteners has further expanded their application scope, providing strong support for improving product appearance quality in various industries.
