PTFE BASED POLYMER LUBRICANT:TESTING OF CHARACTERSTIC PARAMETERS

Abstract

A lubricant is a substance used to reduce friction between surfaces in contact, which 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 surfaces. The property of reducing friction called lubricity. In addition to industrial applications, lubricants are used for other purposes. Other uses include cooking (oils and fats in use in frying pans, in baking to prevent food sticking), biomedical applications on humans (e.g. lubricants for artificial joints), ultrasound examination, medical examinations, and the use of personal lubricant for sexual purposes.
