What is the difference between adding ultraviolet absorber UV - 531 and antioxidant 1010 and adding compound anti - aging masterbatch?

Sunshade nets are usually made of PE and PP as raw materials, compounded with anti-aging master batch and other additives. Some bosses may wonder what the difference is between using the anti-aging master batch and the traditional method of using UV-531 plus antioxidant 1010. On the one hand, when using the anti-aging master batch, the dispersibility is better, and the anti-aging effect is excellent. On the other hand, the anti-aging master batch contains not only these two substances, and it can achieve better effects in a wider spectral range and in terms of performance.
