Application 

XJ-DIBP40 is an active initiator (40% water and methanol based emulsion solution) for polymerization (co)polymerization of vinyl chloride and vinylidene chloride, especially in low temperature to produce  high K-value PVC.

It can also be used in combination with other peroxides such as Di(2-ethylhexyl) peroxydicarbonate (XJ-EHP)  to increase reactor efficiency.
