Question

What are the useful property of plastic ?

Answer 1

Plastics generally have:resistance to corrosion and chemicals, low electrical andthermal conductivity, highstrength-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..........

I hope it's help you

Answer 2

$\large{\boxed{\underline{\bf{\pink{Useful\: properties\:of\: plastic\:are\:as➪}}}}}$

___________________________

$\small{\sf{\green{1.\:Plastic\:is\: chemically\:unreactive }}}$

Plastic are chemically unreactive. Plastics are not affected by the weather. Plastics are also often unaffected by the various chemicals ( also acids and bases ). Since plastics are unreactive and resist corrosion, the plastic containers are used to store various kinds of material, Including many chemicals.

$\small{\sf{\green{2.\:Plastic\: are\:poor\: conductors\:of\:heat\: and\: electricity }}}$

Plastic don't conduct heat or electricity, so they can be used as 'Insulators'. Plastics, being poor conductor of heat, are used where heat is to be kept away from reaching our hands. For example :

The handles of cooking utensils are made of plastic etc.

$\small{\sf{\green{3.\: Plastics\:can\:be\: moulded\:into\: different\:shapes}}}$

Since plastics can be easily moulded, they are used to make large Verity of articles having different shapes and sizes such as bucket, mugs etc.

$\small{\sf{\green{4.\:Plastic\:are \:quite\:cheap\:and\: easily\:made }}}$

Plastics are generally cheaper than metals. Plastics can also be made much more easily than metals. Due to this properties, plastics are now widely used for making many of the household.

$\small{\sf{\green{5.\: Plastic\:is\: light,\: strong\:and\: durable }}}$

Plastics have low density, so they are lighter then metals. Plastics also have good strength and they are durable.
