Application：It may effectively promote the molecular chain breakage of rubber during mastication and prevent free radicals form recombination to large molecules,which can effectually improve the effect of crude rubber plastication.should use it when temperature achieve 120℃or higher.
Processing and dosage: Used as Chemical peptizer for NR & SBR. Add in at the beginning of plastication.It won`t affect the aging cheracteristic of rubber products.No blooming.0.05-0.5% is needed for natural rubber.05.-3.0%is needed for styrene-butadiene rubber.
Storage In original closed containers under cool and dry conditions max. 1 year.
Packing： 25kg one paper-plastic compound bag.
Net weight:25kg/bag.
