Plastics are made from large polymers containing strong bonds, so theyre pretty unreactive. like plastic tubs in microwaves, if it was fairly reactive and weak, it might have melted or exploded.
No, plastics do not corrode. Most plastics do perish and harden over time though. At this point you will fins s dust-like residue on your hands when you rub it over the item. They will eventually start cracking.
the plastics are versatile because they're composed of organic condensation.
Berry Plastics was created in 1967.
Thermosetting plastics
Many parapharmaceutical products are made from plastics.
Hunter Plastics Limited was created in 1967.
When we go to buy any food item we generally use to carry them in plastic as plasctic do not reacts with food items as well as air and water.

Yes.
titanium
it is biodegradle in nature
These are 1- plastics, 2- synthetic fibers and 3- glass
It is normal that using materials which are not corroded corrosion is avoided.
They can be placed safely inside the body, such as with false teeth, eyes etc.
What plastics are there that we use?
These plastics are biodegradable plastics and their name is polycarbonide.
Preheating is necessary for those plastics who are hygroscopic in nature. Mostly all engineering plastics are need to be preheated before processing. If we do not preheat the material than the present moisture in plastics material will react with molten plastic during processing and will cause breakage of polymer chain and results the poor visual appearence (Silver Streaks) & lower mechanical properties of the molded component. Plastics can be preheated thro Hot air oven or Material hopper dryer. And the preheat tempreature may very plastics to plastics. Answer By: Sachin Porwal, Follow me on Twitter: @sachinporwal
Plastics are light due to the
