Calcium carbonate masterbatches based on PP are widely used in plastics industry for manufacturing outdoor (summer) furniture and household appliances, containers, boxes, buckets and so on.
There is no need to modify existing injection molding machines or significantly change machine settings. Depending on existing formulation and specific product application plastic processor can add up to 50% of filler masterbatch into PP resin.
Among the main processing and product quality benefits of use of CaCO3 in injection-molded products are lower shrinkage, better flexural stiffness, higher thermal conductivity, higher impact resistance.
As a new market trend, calcium carbonate filled PP resins proved to be a good substitute for polystyrene and ABS in applications where scratch-resistance is not a requirement.
