Question

Give examples to show that plastics are non corrosive in nature.

Answer 1

Plastics are synthetic or semi-synthetic materials that use polymers as a main ingredient. The term “plastic” is derived from the Greek word “plastikos”, which means “fit for moulding''. The plastics are lightweight, durable, flexible and inexpensive. These characteristics have led to its widespread use.

Complete answer:
Plastics can also be defined as polymers of long carbon chains. plastic is made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process.
There are seven most commonly used plastics, they are
-Acrylic or polymethyl methacrylate(PMMA)
-Polycarbonate(PC)
-Polyethylene(PE)
-Polypropylene(PP)
-Polyethylene terephthalate(PET)
-Polyvinyl chloride(PVC)
-Acrylonitrile-butadiene-styrene(ABS)
Plastics are non-corrosive and non-biodegradable in nature.
Following examples show that plastics are non-corrosive in nature,
They are used to store very reactive chemicals. For example, cleansing chemicals are very reactive and stored in plastic bottles and not in metal containers.
They are used to store all types of food, as it does not react to materials stored in it.
It does not even react with moisture and gets rusted.
Many containers like a bucket, mug are made of plastic since it does not react with water.
It does not decompose when left in the open for a long period.

Note:
Apart from all these advantages keep in note that plastics are very harmful for nature and also for all the living organisms. A plastic cup can take 50-80 years to decompose. When hot food items carried in plastics are consumed it may cause cancer. Hence it is necessary to avoid plastics.
