Get your polymerization off to a fast start.

NPP

Use PPG peroxydicarbonate init ia­tors. They're faster and more efficient than other peroxides commonly used for free radical polymerization. They give high yields, linear conver­sions and low residuals.

We make five types: IPP (di iso-propyl peroxydicarbonate), NPP (d i -n-propy l peroxydicarbonate), SBP (di-sec-butyl peroxydicar­bonate), EH Ρ (d i -2e thy lhexy l peroxydicarbonate), and BPIC ( t -buty l peroxy isopropyl carbonate).

We can custom formulate any of the five, di luted in solvent to your specifications. Important properties and typical applications:
