Iterfort modifiers enhance modified bitumen performances through a chemical process that does not alter the physical structure of the mixture. Bitumen treated with Iterchimica’s modifiers is improved in its mechanical properties (e.g. softening point, penetration, viscosity, etc.).
Special additives used to stabilise modified bitumen: this treatment with Iterfort products increases SBS polymerisation, avoiding the binder’s separation in the storage tank and reducing the sedimentation on the bottom. The higher stabilisation of the binding bitumen-polymer can enable the reduction in the quantity of polymeric additive to be used.
