Plastics that are encountered are generally mixtures. Some are mixtures of polymeric chains of differing lengths such as polyethylene. Some are mixtures that contain not only polymeric chains but have extra ingredients, fillers, plasticisers and coloring agents that modify the properties of the plastic. One example is PVC polyvinyl chloride which is a brittle substance but with the addition of plasticisers (phthalates), becomes flexible.
