Molding
The higher thermal conductivity and lower specific heat of calcium carbonate are key advantages in molding applications.
In injection molding and blow molding operations, cycle time, stiffness and impact resistance will be favorably improved, leading to cost savings.
Blow Molding
Calcium carbonate is used in blow molding applications to produce bottles or containers by offering substantial benefits such as:- Increased flexural modulus,
- Sustained top load and drop impact,
- Improved ESCR,
- Reduced cycle time,
- Lower melt temperature,
- Reduced titanium dioxide amount and
- Improved printability
By selecting a suitable masterbatch carrier resin and appropriate calcium carbonate, producers can make bottles and containers of equal weight and substantially reduce costs.
Injection Molding
Using calcium carbonate in injection molding is a proven solution for improving product properties and productivity. It is widely used in furniture, household appliances and in the automotive industry.The main benefits of using Omya calcium carbonate include:
- Higher stiffness,
- Improved impact strength,
- Less shrinkage,
- More isotropic physical properties,
- Improved dimensional stability and
- Higher heat distortion temperature under load
And thanks to the higher thermal conductivity of calcium carbonate
- Reduced cycle time due to faster cooling
Calcium carbonate addition of up to 50% is recommended.
