WACKER band-ply lubricants (BPLs) are ready-to-use aqueous, solvent-free silicone emulsions. The particular feature of WACKER band-ply lubricants is the ideal balance of outstanding slip in the tire blank and good bleeding properties. The ingredients are carefully composed to prevent the lubricant powder from being removed from the vulcanized tire and the curing bag and so lowers the reject rate in production.
