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.
All plastics, except silicone plastics, are organic.
No, carbon itself is not a type of plastic. Carbon is a chemical element found in all living organisms and is the basis of organic chemistry, while plastics are synthetic materials made from polymers.
Earth's crust is mostly made up of Silicon and Oxygen
The solid layer of the Earth that is made mostly of iron and nickel is called the inner core.
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.
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.
The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
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.
Many parapharmaceutical products are made from plastics.
- 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
