【Product Introduction】
UV absorbent UV-531 has excellent protective effects on polymers and helps reduce color, while delaying material yellowing and hindering the loss of its physical properties.
UV-531 has good compatibility with polyolefins, low volatility, and can effectively prevent loss during processing. It has no impact on the odor of the product itself and has excellent compatibility with thermoplastic resins. It can be evenly distributed within the polymer during processing. UV absorbent UV-531 comes in two forms: powder and flake. The sheet-like UV531 is easy to add in use, can reduce dust flying, is relatively environmentally friendly, and reduces processing difficulty, so it has been widely used.
