SBR Carbon Black Masterbatch containing 100 parts of SBR-1502
base polymer which is prepared with mixed acid emulsifier, 90 parts
of N660 black, 20 parts of naphthenic oil and nonstaining antioxidant
stabilizer.
DIAPOL S920 is widely applicable to extruding
and molding products due to high loading of N660.
