Rubber crosslinking
Rubber compounds containing LQ-BPDH have excellent scorch safety.
Controlled rheology polyropylene
LQ_BPDH is an efficient peroxide for the degradation of polypropylene(CR-PP) in the
temperature range of 200-250℃. LQ-BPDH allows polypropylene producers great flexibility in
controlling a polymer’s Melt Flow Index(MFI).
