Namely calcium carbonate masterbatch, talc masterbatch, calpet masterbatch, chalk-filled masterbatch, concentrated calcium carbonate, CaCO3 composite, CaCO3 granule, CaCO3 extender.
Main Application
Filler Masterbatch is made of high quality Calcium Carbonate and other special additives after extrusion molding from high performance twin-screw machine. It is widely used for polyolefin material in the process of extrusion, injection, plastic blowing, film blowing, casting, etc. When it is put into use, we can reduce material cost, and improve the character of final products.
Technique Index
1. Granule size for Calcium Carbonate: <10um
2. Whiteness: >98%
3. Application ratio: Mix Filler MB with the stuff resin from the ratio of 10% to more than 30% (different ratio decided by the product and user).
Product Characteristics
1. Improve the anti-heating, rigidity and tightness property.
2. Remove the surface light from plastic products, to get sub-light effect.
3. Improve the surface antifriction and antislip property of plastic products.
4. Reduce shrinkage ratio of final products to improve size stability.
5. Reduce fire heating quantity of plastic products to reduce second pollution.
6. Improve surface printing property of plastic to reduce needed electric current under surface corona process.
7. Provide breathe free to film products.
8. Improve heat-conduction property of plastic material to reduce molding period.
9. Reduce the application ratio of white color masterbatch.
Remarks
Stored in ventilated, dry and cool place. Filler MB is easily to absorb moisture from the air. So please use out soon after opening the package.
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.
