Styrenated Phenol (SP) is the
simplest form of a “Hindered
Phenolic” type antioxidant. It is a low activity antioxidant but is used
extensively because other more effective alternatives like Wingstay L®
tend to be very expensive. Antiox BSF is also a hindered phenol and
provides significantly better stabilization for SBR and NBR polymers than
SP. It is effective at lower dosage and therefore stays cost competitive.
It is non-staining, non-blooming and can be used in latex and general
purpose rubbers as well.
It also maintains it’s
effectiveness after vulcanization, thereby continuing to give sustained
protection to the final product that the latex maybe converted to. Use as
substitute for Wingstay C ®.
