PE Calcium Carbonate Additive:

Modify physical property of plastics, act as plastical modifier.

Replace petroleum resource, reduce production cost. Environmentally friendly.

Improve printability, smoothness, hardness, stiffness, anti-block...

PE calcium carbonate additive: used for LDPE/LLDPE/HDPE film blowing/casting, HDPE sheet extrusion, HDPE pipe extrusion, HDPE bottle blowing..., one of additives modifying polyethylene/polythene/polyolefin resin.

Processed by the four paddle rotor internal batch mixer or twin screw extruder.
Calcium carbonate master batch for transparent HDPE film available now. Adding by 5-10%, transparency becomes better in some cases; adding by 10-30%, transparency is still good enough. It's also good for LDPE film, HDPE pipe and PP sheet, which are transparent, but not very transparent.
Rub the film, CaCO3 (powder) and/or talc (powder) are not found.
Pellet is round and flat in shape, smooth feeling, well plastified, good dispersibility.
Ideal additive, harmless, no toxin.
Save cost, reduce expenditure, strengthen competition.
Professional process: CaCO3 (powder) and/or talc (powder) are coated and activated by unique coupling agent, dispersant and plasticizer before CaCO3 (pellet) and/or talc (pellet) are produced.
Special formula: CaCO3 compound and/or talc compound do not apparently side effect physical property of PE film, sometime the tensile strength of PE film becomes better after adding CaCO3 compound and/or talc compound.
Plastic calcium carbonate additive named as CaCO3 filler additive,CaCO3-filled agent,CaCO3 composite,CaCO3 extender,CaCO3 granule.

Benefits of Using Transparent Calcium Carbonate Masterbatch

Maintain the transparency of polymer, keep optical properties almost intact.
Prevent slitting & folding of tapes in tape lines from splitting in machine direction.
Offer extremely good dispersion with any polymer.
Impart certain degree of roughness to extruded/blown film & thereby improve the anti-slip & anti-blocking property of film surface.
Cost reduction when used as a polymer extender.
Improved sealibility in extruded film.
Improve physical properties like hardness, stiffness & impact strength in extruded film.
Decrease extruder torque & increase machine throughput between 5 to 10%. Reduce the energy cost per kg, thereby reduce processing costs.
Replace some of petroleum resources, reduce the burning-heat of finished goods, so that the Burners life-span becomes longer. This reduces energy consumption.
