| PLASTICS FUNCTIONAL MASTERBATCH(PBT) |
| The company selects "ChenZhou"brand antimony trioxide as the main raw material,It can solve the antimony raw material shortage supply problem by Chenzhou strong mining capacity and also the problem on surface special technique processing。Our masterbatch have edges of dust free and good distribution during performance using. As for the advantages above, more and more compounding customers are considering the masterbatch, which has relatively lower cost and dust free as well as better distribution performance. |
