Processability and Mechanical Properties of CB/PVC Composite

In our study, a new kind of material was prepared by melt blending with PVC as the matrix and carbon black (CB) as the filler. With the amount of CB increasing, the notched impact strength of composite increased greatly, however the tensile strength declined. When the amount of CB was 30%, the notched impact strength of composite was 9.66 KJ/m(2), the tensile strength dropped from 48.3MPa to 33.2MPa. The distribution of CB in the PVC matrix is relatively uniform and no large agglomeration in the PVC matrix.
