Types of Lubricants:
Liquid and Non-Liquid Lubricants
There are two main types of lubricants, one being liquid and one the other being non-liquid. Liquid lubricants are characteristically made up of a 90% oil base and contain a variety of liquids in their make-up. The liquid composition allows for improvements in corrosion risk and various effects including wearing and damage through contamination. The other main type of lubricants include non-liquid and include various types of grease various others readily used in plumbing and other well known professions.
Solid lubricants are usually used for lubrication applications running under extreme conditions (e.g. application in the boundary friction area). Setral® has a portfolio of products (MIPO® series) to offer that often can be used as an alternative to molybdenum disulphide (MoS2). The usage can be directly as powder, in suspensions, in pastes, in lubricating greases, in metallic films, in bonded lubricants etc.. Typical applications are e.g. anti-friction linings, rubber, plastics etc..
Pastes are used in very slowly running bearings (rolling and plain bearings), under simple sliding procedures, as assembly pastes, separating agents or as high temperature pastes at temperatures above +300°C (evaporation of the base oil). The use of solid lubricants make pastes suitable for extreme heavy load applications. In the broad range of pastes of Setral® the MIPO® technology is used for the improvement of the separation and lubricating properties.
Greases are the “all-rounder” among the lubricants and find use in practically every industry. They cover broad ranges of temperature, speed and load. Application areas can be in dry, dusty as well as wet, corrosive environments.
Additives are used to support or improve existing properties of the lubricant/base oils. This includes e.g. oxidation stability, load carrying capacity (EP-properties) or lubricity. They can also be used to generate additional properties such as corrosion protection, wetting properties, flow at low temperatures. Producing special lubricants requires the use of synergistic combinations of different additives.
