Calcium carbonate filler for nonwoven materials

CaCO3 filler for non-wovens

We offer special grade CaCO3 filler mastrebatch for non-woven fabric.

Latest developments and researches made by calcium carbonate makers outlined a number of benefits of use of CaCO3 fillers in non-woven fabric intended for hygiene, medical, personal care, geotextile, industrial and many other applications.

Calcium Carbonate in Blown HDPE Film

Many interesting developments have taken place in the film industry over the past few years due to new improved resins and the increased capability of extrusion lines.

Technical progress must however be subject to the cost factor and the use of mineral modifiers, especially calcium carbonate can play an important role. Most polymers are ductile but may become brittle under certain circumstances.

Calcium carbonate filler for breathable films

The use of mineral fillers in the fabrication process of breathable films has allowed a considerable development of these type of films, especially for hygienic films. 
Calcium carbonate is in this special case active ingredient giving the film special characteristics which allow it to breathe thanks to the network of micropores.

The whitepaper addresses use of calcium carbonate in breathable films covering market trends and product requirements.

Effect of Calcium Carbonate on specific film properties

The addition of minerals always affects the properties of film or sheeting. It is therefore all the more important for manufacturers to obtain precise information about the minerals they use.

This technical papers describes the effect of calcium carbonate on properties such as light transmission, light ageing, permeability to water vapour and other gases, and stress-crack resistance.

Calcium carbonate filler for extrusion of yarn and twine

PP twine

One of the main issues the producers of weaving tapes (yarn) and twine face during production is a so called fibrillation effect – an uncontrolled splitting of stretched PP/PE yarn (tape). Using calcium carbonate in the composition helps to reduce or completely avoid fibrillation. Slight modification of your original formula by adding 3-4% of calcium carbonate filler masterbatch is enough to solve the problem.

Calcium carbonate filler masterbatch in injection molding

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.

Topic: 

Is calcium carbonate thermally conductive?

Calcium carbonate has remarkably higher thermal conductivity as compared to the polymer (6 and 14 times higher than those of HDPE and PP respectively). This means that the heat generated during plastic processing is transmitted through the mixture more quickly allowing faster heat transfer in extruder (faster melting & more homogeneous melt temperature), leading to potential energy savings during extrusion.

Topic: 

Cheap calcium carbonate filler masterbatches

Calcium carbonate filler masterbatches we offer is the most effective cost-saving solution 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.
