Cobalt Aluminate Blue Spinel Blue pigment 28 is an inorganic pigment called Cobalt Blue, which is regarded as a key component of high-performance pigments in the plastic processing field.
The main advantages of plastic applications are as follows:
1. Excellent thermal stability
Plastic processing usually requires high temperatures (for example, nylon may exceed 300°C). Blue pigment 28 has special heat resistance and can be used at temperatures above 1000°C without color change or decomposition.
Application advantages: Suitable for all engineering plastics (such as PA66, PBT, PC, etc.), while maintaining color stability, ensuring long service life even during injection molding.

2. Excellent light resistance and UV resistance: Cobalt blue has natural chemical inertness and has the best light resistance and weather resistance (8-level light resistance, 5-level weather resistance).
Application advantages: It is the preferred material for outdoor plastic products (such as sports stadium seats, outdoor building materials, automotive parts), and will not change color or crack even when exposed to sunlight for a long time.

3. Chemical inertness and non-migration
Blue pigment 28 is insoluble in water and most organic solvents, and has excellent resistance to acids, alkalis, and chemical corrosion.
Application advantages: It does not cause "migration" or "coloring" phenomena. Due to its extremely high chemical stability, it is often used in PVC plastic packaging that comes into contact with food.

4. Low shrinkage rate and dimensional stability
Many organic pigments, such as phthalocyanine blue, cause plastic components to shrink or deform during crystallization, especially more obvious in large injection molded parts.
Application advantages: Blue cobalt has an inorganic crystal structure and does not promote polymer crystallization, effectively preventing plastic products from deforming and ensuring the stability of precise component dimensions.

5. Environment and safety
Blue pigment 28 contains cobalt and is an inorganic composite pigment with a corundum structure (CPIC), where cobalt ions are tightly bound to the crystal lattice, having strong physiological inertness.
Application advantages: It complies with most countries' environmental regulations (such as RoHS and REACH), and is widely used in high-safety toys and food packaging plastics.
