Plastics are a sub-group of chemicals in a field of chemistry called Organic Chemistry. Organic Chemistry focuses on a base element called Carbon and the way it is able to join with other chemical elements by bonding. They(Plastics) usually are referred to as Polymers and are often produced from bye-product or left over of fuel refining. It is also possible to create Plastic from cellulose,pullped from a component of the microscopic cell walls of plants(e.g. trees).
Some plastics dissolve in acetone, like styrene. Others don't - nail polish remover comes in plastic bottles, so there are plastics that will hold it.
Yes Acrylic plastic is reversible. Acrylic comes in any forms, Plastics and paints are the most common, Acrylic plastics can be melted down and reformed.
The word "plastic" is an old word meaning something along the lines of "moldable". Many materials commonly called plastics are moldable, at least if you heat them up (not all of them, though; it always gives me a little twinge to hear someone call a material like Bakelite "plastic" ... it will burn before it softens or melts).
What plastics are there that we use?
they are plastics that can be bad for our environment
Plastics are light due to the

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.
we can join plastics by burnig
Many plastics are.
You can separate plastics by color to make it easier for recycling companies. You can also separate it by the types of plastics.
three types of thermo plastics are POLYETHENE.....,POLYPROPYLENE........and.......POLYVINYL CHLORIDE(PVC)
