Antioxidant NBC (CAS: 13927-77-0) Applications
Antioxidant NBC is used as an antiozonant in chloroprene rubber, chlorosulfonated polyethylene rubber, styrene-butadiene rubber, and nitrile rubber.
In chloroprene rubber, NBC improves the rubber's heat resistance, reduces discoloration in sunlight, and slightly delays vulcanization.
Antioxidant NBC is also a heat stabilizer in chlorosulfonated polyethylene rubber vulcanized with metal oxides.
The typical usage is 1-2 parts in chloroprene rubber and 0.5-3 parts in styrene-butadiene rubber.
