LEYBONOL greases are solid to semi-solid substances which consist of the principal components base oil and thickener. The base oil provides most of the lubrication and will in most cases define the service temperature. The thickener binds the oil and can increase the lubricity or the thermal stability of the grease. Added to these two constituencies are additives which may improve the performance of the grease in specific areas depending on the specific application. Greases will reduce friction and wear, ensure movability of components, will seal off against contaminants or are used as anti-rust and anticorrosion agents.
