Question

What are the characteristics of plastic?

Answer 1

Hint: A plastic is a material that has the ability to change shape. Plastics are used for a variety of purposes, primarily because shaping them into the desired shape is simple. Plastic comes in a variety of forms. Some can only be shaped when they are freshly made, after that, they harden.

Complete answer:
Plastics have the following properties:
Tensile strength: The tensile strength or hardness of plastics is determined by the materials used in their manufacture. As compared to alloys like steel, plastics usually have lower tensile strength or durability.
Lightweight: They are lighter than metals, making transportation and transporting them from one location to another easy.
Reactivity towards chemicals: As opposed to natural polymers such as cotton, wool, and so on, plastics are unaffected by acids and alkalis.
Appearance: Plastics are usually translucent and can be coloured to a variety of colours. They can also be moulded into different shapes depending on their intended use.
Thermal conductivity: Plastics have a poor thermal conductivity. That's why they melt when they come into contact with fire.
Electrical Conductivity: Plastics are either good insulators or poor conductors of electric current, depending on their electrical conductivity. Plastic's property or characteristic makes it common in the manufacture of switches, bulb holders, and the outer covering of wires, among other things.

Note:
The chemical composition of the polymer's backbone and side chains is used to classify plastics. Acrylics, polyesters, silicones, polyurethanes, and halogenated plastics are some of the most important classes listed this way.
