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 12 combines alcohol and ester lubricity technologies with an oxidation inhibitor, for aluminium cold rolling oils. It has a neutralisation number below 0.1 mgKOH/g and a pour point of 18°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.
