Will there be color difference when mixing stranded rubber? How to solve it? Is there any company consultation in this field?

This may be a matter of color masterbatch. At the beginning of rubber mixing, it should be proportioned, and the temperature and time should be controlled well. This also requires a professional colorist, or it may be a problem for the colorist. After all, he is operating it, and there is something wrong with your formula. If the formula is not well prepared, it's no use doing it again. Besides, what color are you making? If it's fluorescence, there's nothing to do. Originally, fluorescent color is dye-grade, which is not temperature-resistant or heat-resistant. If there is such a problem, you should first find your seller and let that company solve it. If it can't be solved, Shenzhen Tyco Science and Technology City is an expert in this field.
