Because most plastics are made very differently from one another it would be best if we had a clear idea of which will fit into your presentation.
Polystyrene is an obvious choice if you're talking about construction. Then again,
Polyvinyl chloride might be better because they make PVC pipes and vinyl siding. The point is, even these two examples are made differently and to tell you how one is made is not going to be the same as the other.
Plastics are not really a substance that has an overall manufacturing outline to it. It would be hard to try and present one. Can we focus on a particular example?
