Antioxidant B Rod
B Rod is an excellent general purpose staining antioxidant. It confers very good heat resistance and good flex cracking resistance. It disperses readily in rubber and does not bloom. It is used in automotive tubes, curing bags and in mechanical rubber goods. B Rod is suitable for use in latex compounds. Typical dosage varies from 0.25-2.0 phr although in exceptional circumstances up to 3.0 phr may be used to confer high heat resistance without bloom. It also possesses metal inhibition properties to some extent and recommended for cable insulations, rubber to bra ss bonding, hoses and latex foam, gloves & coir mattress compounds.
