Papua New Guinea MB-80 of pre-dispersed antioxidant

Pre-dispersed antioxidant MB-80 is mainly used as a synergistic agent of other antioxidants, and the combined effect of other antioxidants is usually better than the sum of their effects when used alone; it is a medium-strength non-polluting antioxidant, especially suitable for compounds containing overspeed accelerators and heat-resistant compounds containing no sulfur but containing thiuram TMTD-80; when MB-80 with sulfenamide CBS -80 or thiazole MBT-80 or thiuram and dithiocarbamate accelerators, the pre-dispersed antioxidant acts as an anti-scorching agent to improve the processing safety and storage stability of the rubber compound. However, the pre-dispersed antioxidant MB-80 slightly reduce the modulus of NR and synthetic rubber products. If the dosage is recommend, no blooming will occur.

Product characteristicsPre-dispersed antioxidant MB-80 is mainly used as a synergistic agent of other antioxidants, and the combined effect of other antioxidants is usually better than the sum of their effects when used alone; it is a medium-strength non-polluting antioxidant, especially suitable for compounds containing overspeed accelerators and heat-resistant compounds containing no sulfur but containing thiuram TMTD-80; when MB-80 with sulfenamide CBS -80 or thiazole MBT-80 or thiuram and dithiocarbamate accelerators, the pre-dispersed antioxidant acts as an anti-scorching agent to improve the processing safety and storage stability of the rubber compound. However, the pre-dispersed antioxidant MB-80 slightly reduce the modulus of NR and synthetic rubber products. If the dosage is recommend, no blooming will occur.

Processing characteristicsUnder normal circumstances, powdered MB is easy to fly and adhere to equipment, and is not easy to disperse evenly during mixing, resulting in defects in rubber products. However, the pre-dispersed antioxidant MB-80 is easy to mix and mix, will not agglomerate under normal storage conditions, has good fluidity, has no dust flying during rubber mixing, and will not cause feeding loss. Rapid mixing, absorption and uniform dispersion in various rubber materials ensure the activity of effective component MB.
