Plastic sheets and thermoforming

Calcium Carbonate Masterbatch (CaCO3) for the manufacture of thermoformed sheets

Save by using it in the production of thermoformed plastic sheets (trays, vessels, plates and plastic covers)

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 the 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
  • Reduction of cycle time due to the higher thermal conductivity of the CaCO3
  • Helps to reduce thickness
  • The PLASPER® concentrates produce a whitish appearance, which saves the use of TiO2
  • Using 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)
  • Facilitates welding
  • Improves the processability/transformation and the extrusion performance
  • Improves dispersion
  • Improves the impression of the final product

Improves properties

  • Increases rigidity
  • Increases impact resistance
  • Improves the barrier effect
  • Promotes the anti-blocking effect
  • Improves the mechanical properties

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® series does not require any change 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%
