Plastics are made from oil - the same kind that is also processed to form gasoline, jet fuel and many other things. Oil (and plastics) is a mixture of long chained hydrocarbons (compounds made mostly of hydrogen and carbon).
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.
Plastics are made from more than one element and therefore are compounds.
The atmosphere is made mostly of gas. Why is what I am trying to find out people!
the effects is that when you burn plastics which are made from polymers it creates pollution which produces carbon dioxide which contributes to global warming. Also plastics are non biodegradable and so landfills are used to bury the plastic this takes up space and also costs money because there is not enough room for all the waste. Therefore plastics are banned in some area.
The earth is mostly made of water because the world is water with land.
Deodorant cans are mostly made from plastics.
No. Plastics are mostly made from fossil fuel oil, so they're not renewable and they're not natural either, but man-made.
Mostly polyester resin, but some epoxy as well. Small dinghies can be made of thermoset plastics.
mostly thermosetting plastics like bakelite
Many plastics are.
the plastics which are used are mostly very strong, light and sturdy because of the particles and polymers in the plastic itself.
The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
No, it's an exceedingly unnatural material. For complicated reasons, if you polymerize ethylene, you get polyethylene, but if you polymerize propylene, you get ... polyethylene again. You have to use trickery (usually in the form of a Ziegler-Natta catalyst) to get polypropylene.
Many parapharmaceutical products are made from plastics.
the plastics are cheap, durable and easily made into intricate shapes.
- 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.
theyre made out of cheap plastics
