Question

Which properties of plastic make it a material of choice

Answer 1

Answer:

Plastics generally have: resistance to corrosion and chemicals, low electrical and thermal conductivity, high strength-to-weight ratio, colors available in a wide variety and transparent, resistance to shock, good durability, low cost, are easy to manufacture, resistant to water and have low toxicity.

Answer 2

$\huge{\underline{\red{\sf{Answer:}}}}$

→ Plastics show following properties -

1) Light weight - In comparison to other materials plastic is quite less in weight.

2) Chemical reactivity - Plastics do not easily react with acids or bases.

3) Apperance - Plastics can be seen in many colours , different shapes and wide variety, from small in size to large size.

4) Weather resistance - plastics are non biodegradable i.e. why , they do not change with weather unlike natural fibres like cotton, and wool.

5) Solubility - Insoluble in water , therefore remains unaffected.

6) Tensile strength - Plastics vary in their tensile strength from material to material. plastics have much less toughness as compared to metals and alloys like steel.

→ Due to these characteristics PLASTIC IS CONSIDERED AS MATERIAL OF CHOICE .
