The process of compounding involves mixing, blending and/or reacting upon the collected ingredients required to produce a finished product. For example, a compounded plastic resin or elastomer compound typically consists of base polymer resin(s), chemical additives, and reinforcing or extending fillers. A wide variety of materials may be created through compounding including plastics, rubber, elastomers, cleaning agents, lubricants, greases, masterbatch colorants (pigments, dyes), additive masterbatches, organic chemicals, chemical additives, metal working fluids, oils, oil and fuel additives, fuel mixtures, and other materials.
