Wyrol is ExxonMobil's range of liquid additive concentrates for optimising the frictional characteristics of cold rolling oils such as the Somentor Series, letting aluminium rolling mills fine-tune performance and achieve the required surface finish and substrate quality. Wyrol 2 is the oxidation inhibitor concentrate of the range: it extends the life of the roll oil. It has a kinematic viscosity of 2.2 mm2/s at 40°C and a density of 830 kg/m3 at 15°C. It is designed to comply with FDA 21 CFR 178.3910(a), suiting use in rolling foil or sheet stock for food applications. Benefits include a high degree of flexibility to fine-tune roll oils for optimum mill performance, extended roll oil life, improved finished product quality, and reduced reject and waste material. For best performance, store the product in a warmer (30°C) environment for 24 hours before use if it was previously stored below 5°C for an extended period.
