Waarom anorganische pigmenten gebruiken voor technische kunststoffen?
Engineering plastics are often used in applications that require high performance and durability. To achieve the desired color and appearance, engineering plastics are often colored with pigments.
Inorganic pigments are a common choice for coloring plastic because they offer a number of advantages over organic pigments.
Inorganic pigments are:
1. Heat resistance. Inorganic pigments have a high melting point and are less likely to decompose at high temperature. This is important for engineering plastics, which are often processed at high temperatures.
2. High strength. Inorganic pigments have high tinting strength, which means they can be used to achieve a wide range of colors.
3. Stability. Inorganic pigments are stable in a variety of environments, including light, heat, acid, and alkali. This means they are less likely to fade or change color overtime.
4. Non-toxic. Inorganic pigments are typically non-toxic and meet food-grade and medical grade standards.
For these reasons, inorganic pigments are the most common choice for coloring plastics.
