Revise: Polymer Sources and Geographical OriginsMany manufactured polymers begin with crude oil, rather than with a ready-made plastic. Crude oil is extracted from underground deposits by drilling wells. It supplies chemical raw materials used to manufacture both thermoforming and thermosetting polymers.
- Revise: Geographical Origins of Components
A naturally occurring mixture extracted from underground and refined to provide chemical starting materials for polymers such as acrylic, HIPS and ABS.
