In plastics and powder coating applications, heat resistance is critical. Standard pigments may discolor under high processing temperatures.
That’s why high heat resistant pearlescent pigments are essential.
Heat Resistance Requirements
Typical processing temperatures:
- Injection molding: 200–300°C
- Engineering plastics: up to 320°C
- Powder coating curing: 180–220°C
High-grade pigments maintain:
- Color stability
- Pearl effect
- No blackening
Applications
- Automotive plastic parts
- Appliance housing
- Powder coated metal
- Industrial components
