Question

List any four properties of plastics and their applications based on those properties.

Answer 1

The four properties of plastics and their uses are:
1) Plastics are poor conductors of heat and electricity. That is why they are used to make handles of cooking utensils and coverings of electrical wires.

2) Plastics are non-corrosive. They usually do not react with most substances. That is why plastic containers are used to store chemicals, food items, medicines, etc.

3) Plastics can be easily moulded into different shapes. That is why they are used to make a large variety of objects with different shapes and sizes such as toys, buckets, furniture, toothbrushes, bags etc.

4) Plastics are cheap, light, strong and durable. That is why they are preferred over metals for certain applications in automobiles, aircraft and spacecraft.
