Extender oil is used to improve the mechanical properties and other important properties of natural and synthetic rubbers, as well as in automotive tire production. Extender oils have high levels of Polycyclic Aromatic Hydrocarbons (PAHs), which have a carcinogenic effect on human health. The European Parliament has imposed a prohibition on the use of carcinogenic extender oils. Green automotive tire production uses carcinogens treatment technology aimed at producing environmentally safer tires.
Vaisala K-PATENTS® Process Refractometer PR-43-GP provides real-time indication of the aromatic content of the oil stream, which strongly correlates with PAH concentration.
