Abstract:
A steel cord comprises a core with one or more core steel filaments and further comprises a first layer of intermediate steel filaments twisted around the core, and a second layer of second steel filaments twisted around the first layer. At least one of the intermediate steel filaments is individually coated by means of a polymer with a minimum thickness of 0.010 mm. The polymer reduces the fretting between the coated intermediate steel filaments and the other steel filaments and makes the steel cord suitable for reinforcement of carcass plies of a tire.
