What are some different thermoplastic plastics?
These are plastics which are softening while temperature increases. Such property makes forming of end products easy. Examples are: Polyethylene, Polypropylene, Polystyrene, Polytetrafluoroethylene also known as Teflon, Polyvinyl chloride (PCV) to name few popular.
Are all plastics petrochemicals?
No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.
Are plastics made from crude oil sustainable?

How are biodegradable plastics made and what are the problems with them?
- Some plastics made from starch are biodegradable- Another bio-oxodegradable plastics contain a catalyst ( as iron oxide) which improve the degradation in contact with oxygen.Generally biodegradable plastics are as foils not containers.
What is the dsi made of?
