Abstract
This chapter presents a brief discussion of additives impact on the surface treatment of materials. The authors discuss important additives and the properties and characteristics that they impart to surfaces of materials (thermoplastics, rhermosets and elastomers) in which they are compounded. It is possible to argue that all materials can be compounded with additives. In practice plastics and elastomers are the only hosts to additives with rare exceptions. Whether an additive affects the surface properties of a polymeric material (plastic, elastomer or thermosetting) depends on a number of factors. Additive and polymeric material properties and processing methods affect the surface properties of the parts made from them. Of prime importance is the surface energy of the material containing the additive(s). Fluoropolymer and silicone additives have the strongest impact on the surface energy of polymeric materials to which they are added.
