Question

Why plastic dosenot rust like iron

Answer 1

Answer:

look below

Explanation:

As we know that rusting takes place due to the oxidation, when the water vapors react with the surface of the iron. In the plastic they don't react with the surface at all.Hence plastic does not get rusted.

Answer 2

Answer:

Plastics, more accurately called polymers, are not metallic so they don't corrode as such. However, the do suffer from environmental degradation. Polymers degrade in the environment because some agent causes the covalent atomic bonding in them to break down.

So, Rusting takes place only due to the oxidation, when the water vapours react with the surface of the iron or a metal. In the plastic they do not react with the surface.So plastic does not get rusted
