Answer 1

Hi there
Plastic one of the rubbery as well as a strong polymer which cannot be decomposed on earth.
This is used to make many of the articles and toys because it is chemically made and is economically cheap.
Plastics can be moulded in any shapes and sizes depending on the moulds when it is hot atleast maintaining 300 to 1200℃ of temperature...
Hope this will help u dear☺☺
