We supply and export calcium carbonate compound and talc compound.

• Namely calcium carbonate masterbatch, talc masterbatch, calpet masterbatch, chalk-filled masterbatch, concentrated calcium carbonate, CaCO3 composite, CaCO3 granule, CaCO3 extender.
• 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 and replace the resource of petroleum, reduce the burning heat and fume, protect the incinerator, environmentally friendly.
• Save cost, reduce expenditure, strengthen competition.
• Improve and modify physical property of plastics: more smoothness of surface, easier and better printability, harder and stiffer, anti-block. Act as plastics modifiers.
• 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.

PE grade

serie	MI ( g/10min)	application & adding ratio recommended	feature for film blowing
01	2.3	film blowing 10-30% film casting 5-40% mulching film 5-15% blowing mould 20%	very high adding ratio, not side effect tensile strength
02	4.0	film blowing 10-35% blowing mould 10-20%	excellent hand-feel & superior smoothness of film
03	4.5	film blowing 10-30%	good for transparent HDPE bag

• In general, CaCO3 masterbatch (PE grade) is suitable for PP products as well.

PP grade

• Mostly popular for rafia sacks and rafia bags.

ABS & PS grade

• EVA grade, PVC grade and nylon grade available as well.
• Adding ratio recommended for reference only, please adjust it up or down based on experiment and experience.
• Formula could be tailor-made upon request in order to satisfy with higher or lower price.
• Refer to "ingredients" above, if carrier is LDPE, it does not mean it's suitable for LDPE bag only; if carrier is HDPE, it does not mean it's suitable for HDPE bag only.

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.
