The partial substitution of talc for carbon black in various automotive parts provides a level of performance required to meet the challenges of today and in the future.  Talc as an insulator eliminates the electrochemical degradation in coolant hose and the electro-corrosion of seals.  Replacement of carbon black with talc also reduces weathering in exterior parts, improves thermal performance in under-the-hood applications, and reduces permeability of fuel and refrigerant in hoses.  In addition, talc improves processing without compromising the mechanical properties.
