Heat capacity, density, surface tension, and contact angle for polyalphaolefins and ester lubricants

• Thermophysical and surface properties of eight different lubricants were measured. • The behaviour of polyalphaolefins and ester-based lubricants were compared. • Heat capacity values were used to test the validity of two predictive methods. Thermophysical properties of lubricants are important to understand which ones are appropriated for the industrial conditions expected. Thermophysical properties of two different families of lubricants...
