The higher thermal conductivity and lower specific heat of calcium carbonate are key advantages in molding applications.
The cycle time, stiffness and impact resistance will be favorably improved in injection molding and blow molding applications, which then leads to cost savings.
Blow molding
Calcium carbonate offers substantial benefits in blow molding applications for producing bottles or containers, such as:
- Increased flexural modulus
- Sustained top load and drop impact
- Improved ESCR
- Reduced cycle time
- Lower melt temperature
- Reduced titanium dioxide content
- Improved printability
Injection molding
The main benefits of using Omya calcium carbonate include:
- Higher stiffness
- Improved impact strength
- Less shrinkage
- Improved dimensional stability
- Higher heat distortion temperature under load
- Cycle time reduction
Specialty chemicals
- Flame retardants
- UV stabilizers
- Antioxidants
