| We offer for export nano-grade calcium carbonate, heavy calcium carbonate and light calcium carbonate
Nano-grade calcium carbonate
Molecular
formula: CaC03
Color: White
Appearance: Powder
Main uses
Widely used in plastic, paper making, paints, rubber, electronics,
cosmetics and food etc.
Especially use for improving the mechanic performance of polymer
composite ,
In PVC electrical cable and wire,PVC Building Materials, PVC plastic
granule and glue granule making etc.
Advantages:
High brightness, purity and Low impurity
Active dispersion and High surface activity
Small grain size, Stable crystal form,and Wide distribution of grain
size.
Have great affinity with PVC, have double effects of filling and
reinforcing action
Main diameter between 40 nm and 80nm, can instead of Titanium Dioxide in
some industry.
Can help to reduce the production cost and improve competitiveness.
