This chapter describes the properties and attributes of various classes of metalworking lubricants, including mineral oils; natural oils, fats, derivatives, and soaps; synthetic fluids (olefins, esters, polyglycols, ionic liquids); compounded lubricants (oils, greases, fats); aqueous lubricants (emulsions, synthetics, solutions); and a wide range of coatings and carriers. It also discusses solid-film lubricants (oxide films, polymer films, layer-lattice compounds) and environmental and safety concerns.

This article covers the thermal analysis and thermal properties of engineering plastics with respect to chemical composition, chain configuration, and/or conformation of the base polymers. The thermal analysis techniques covered are differential scanning calorimetry, thermogravimetric analysis, thermomechanical analysis, and rheological analysis. The basic thermal properties covered include thermal conductivity, temperature resistance, thermal expansion, specific heat, and the determination of glass-transition temperatures. The article further describes various factors influencing the determination of service temperature of a material. Representative examples of different types of engineering thermoplastics are discussed in terms of structure and thermal properties. The article also discusses the thermal and related properties of thermoset resin systems.
