Antioxidant BL
BL provides a combination of excellent resistance to flex cracking and heat ageing. It is specially suited for tyres, belting and a wide range of mechanical rubber goods. It is a staining antioxidant and may stain by migration.
Typical dosage varies from 1.0 - 3.0 phr without any blooming. In tread rubber compounds which are required to store at room temperature for prolong periods, BL plays an important role in suppressing sulphur blooming in these compounds. Being readily dispersible, it is usually better to use BL in soft rubber compounds like cushion gum etc. It could be used as a stabilizer for production of oil extended SBR.
Storage and Handling
Stable indefinitely under normal storage conditions. No special precautions are necessary. Normal precautions to avoid contact with skin and eyes should be followed. Skin contamination: Wash liberally with soap and water. In case of contact with eyes rinse immediately with plenty of water and seek medical advice.
