The calcium carbonate filler masterbatches we offer are the most effective cost-saving solutions for worldwide plastic processors.
CaCO3 filler masterbatch not only cuts down plastic production costs by replacing a part of virgin polymer during extrusion, injection and blow molding, but also increases output, improves production conditions as well as a number of physical and chemical properties of finished plastic products.
With a variaty of choices in the market CaCO3 filler masterbatches may remarkably differ in quality due to different formulations (CaCO3 content, carrier polymers type & content, chemical additives), compounding technologies as well as technical team skills they were made with/by, even in the same country or geographical area.
A number of factors must be considered to evaluate overall CaCO3 filler quality. Average particle size, top-cuts and calcium carbonate content are the most important ones to influence filler price so we may generally classify fillers based on them as:
Economy fillers – low price calcium carbonate filler masterbatches (concentrates) with comparatively coarse CaCO3 particles (D50 of <3µm in average)
Standard fillers – middle price calcium carbonate filler masterbatches (concentrates) with fine CaCO3 particles (D50 of <2µm in average))
Advanced fillers – high price calcium carbonate filler masterbatches (concentrates) with ultra fine CaCO3 particles (D50 of <1µm in average)).
