Calcium Carbonate Masterbatch (CaCO₃) for the manufacture of twin wall sheets

The PLASPER® Calcium Carbonate Masterbatch is a mineral modifier with a high, very fine, treated CaCO₃ content that has an excellent dispersion in the final product, indicated for direct addition in the processing of polyolefins. The PLASPER® mineral modifier is designed to increase productivity, reduce energy costs and improve properties of sheet.

ADVANTAGES

Economic saving

• Reduction in energy consumption
• Reduction in raw material costs of 3% to 20%, depending on the percentage of PLASPER® used
• Helps to reduce thickness
• The PLASPER® concentrates produce a whitish appearance, which saves the use of TiO₂
• Using the PLASPER® CaCO₃ MB allows the transformer to have control over their formulations, which allows for more flexibility in the purchase of raw material

Improvements in productivity

• The CaCO₃ increases the thermal conductivity of the minerals, which results in more rapid heating and cooling of the polymer (Fig. 1)
• Better dimensional stability, increase in production and easier transformation
• Improves the processability/transformation and the extrusion performance
• Improves dispersion
• Improves the impression of the final product

Improves mechanical properties

• Increases rigidity
• Increases impact resistance

Environmentally friendly

• Carbon footprint smaller than the virgin polymer
• Products are more environmentally friendly and sustainable with the use of PLASPER® CaCO₃

RECOMMENDATIONS FOR USE

• The application of the PLASPER® Masterbatches does not involve any modification to the production process
• The most suitable dosing systems are:
  • Gravimetric dosing unit
  • Volumetric dosing unit (the best way is to use the feeder at the neck, between the hopper and the extruder)
  • Centralised mixing stations also give good results
• Dosing: between 3% and 20%
