WebSep 7, 2024 · Bio-lubricants or biodegradable lubricants are suitable to solve the following industrial problems: Reduce mechanical energy losses. Reduce wear on friction parts. Provide protection to the parts against corrosion. Reduce the working temperatures of the machines. Increase the tightness of seals. Avoid spilling deposits of impurities and dirt. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the … See more Lubricants have been in some use for thousands of years.
