Application

1. Rubber crosslinking

Rubber compounds containing BPDH have excellent scorch safety.

2. Controlled rheology polyropylene

BPDH is an efficient peroxide for the degradation of polypropylene(CR-PP) in the temperature range of 200-250℃. BPDH allows polypropylene producers great flexibility in controlling a polymer’s Melt Flow Index(MFI).
