Plastic Classifications

07/11/2012 4:59 PM

Hi everyone, Im trying to learn about the world of plastics.

The thing Im finding hard is breaking down the classifications of plastic.
I have found plastics can be classified by chemical structure. I have also discovered that some important groups are:
Halogenated plastics, polyesters and polyurethanes.

Can anyone explain, what is a halogenated plastic?
How many classifications of plastic are there?
If you tried to constuct a familey tree for plastics does it break into themosetting/thermoplastics then further divide?

Thanks for any help anyone can provide with this.

Start here: Plastic - Wikipedia, the free encyclopedia

This subject is even more complex than metals and it cannot be explained in 500 words or less. You will have to do considerable research on your own, then come with questions, not requests for an education.
