Calcium carbonate (77% CaCO3) filler masterbatch for PE AF771E

AsiaFiller AF771E is a highly filled calcium carbonate filler masterbatch (concentrate) containing ultra fine pure CaCOin polyethylene matrix and special additives.

This CaCO3 filler masterbatch is intended to be added into polyolefin compatible resins during extrusion, injection or blow molding to displace a portion of the resin, thus cutting down the costs while improving product properties.

Adding ratio may typically range from 5% to as high as up to 60% depending on the particular product and processing conditions.

In blown PE films application typical film thickness to start from 6 micron.
