Modify physical property of plastics, act as plastical modifier.

Replace petroleum resource, reduce production cost. Environmentally friendly.

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

PS chalk masterbatch: used for PS sheet extrusion, PS injection mould..., one of masterbatches modifying polystyrene 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 chalk masterbatch named as chalk compound,chalk additive,chalk-filled extender,granulated chalk-filler composite,plastic CaCO3 agent,CaCO3 extender,CaCO3 granule.

  • EVA grade, PVC grade, nylon grade, tubing & Pipe grade and non-woven fabric 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.
