you know heat makes something expand and cold makes it contract. When injection molding the plastic material is hot, so it expands and when it is cold it shrinks. That is why how shrinkage comes.

When you crush a plastic bottle, you decrease the volume inside the bottle. This increase in pressure (due to the decrease in volume) is what makes the bottle crush. The atmospheric pressure outside the bottle remains constant, causing the bottle to collapse under the increased pressure inside.
An insulator material such as rubber or plastic hinders the passage of electric charge because it does not allow electrons to flow freely. This property makes insulators useful for insulating and protecting electrical wires and components.

A common example of a molded material that can retain its shape is plastic. When heated and molded into a specific form, plastic cools and solidifies to maintain that shape. This property makes plastic widely used in manufacturing for various products due to its durability and versatility.
Copper and brass
It's a non-conductor (of electricity).
Plastic is elastic due to its molecular structure, which allows its polymer chains to stretch and return to their original shape. This property makes plastic flexible and able to deform without breaking, making it ideal for a wide range of applications.
flexible and stretchy
A material through which nearly all light passes is called a transparent material.
Not all rulers are made of plastic, you can get examples that are made of wood or even metal. However, plastic is a material that is easy to mould and this makes plastic rulers cheep to purchase. You can also see through some of them which makes them easier to use.
