A limestone powder in plastic:
1, incremental and reduce costs.
2, to improve the heat resistance of plastics, 40% CaCO3 added to the polypropylene, the heat distortion temperature can be increased by about 20 ℃.
3, to improve the astigmatism of the plastic, and play the role of shading or extinction.
4, to improve plating performance of the plastics or printing performance.
Reduce the size of plastic products shrinkage and improve dimensional stability.
In addition, the activity of calcite powder, can also greatly improve the processing flow, increase filler content, and to improve the mechanical properties of CaCO3-plastic composite system, in particular, impact strength and elongation at break.
Limestone mining industry more and more attention has been paid. Henan Liming Heavy spring t cone crusher, the use of advanced technology, it is worth your trust.
