Mention some characteristics of plastic
Answers
Answer:
Plastic is chemically unreactive:Plastics do not react with air and water. ...
Plastics are poor conductor of heat and electricity:They do not conduct heat or electricity,so they be used as insulators. ...
Plastics can be moulded into different shapes. ...
Plastics are quite cheaper and easily
Answer:
Mark me brainliest
Explanation:
Tensile strength: The tensile strength or the toughness of the plastics are dependent on the materials that are used in the production of the plastic. Usually, the tensile strength or the toughness of the plastics are less when compared to the alloys such as steel.
Lightweight: They weigh less than that of the metals which makes their transportation easy or carrying them from one place to another becomes easy.
towards chemical Reactivity: When plastics are compared with natural polymers such as cotton, wool, etc, plastics are not affected by the acids and alkalines.
Appearance: Usually plastics are transparent and can be coloured to desirable colours. Also, they can be moulded into shapes depending on their usages.
Thermal conductivity: The thermal conductivity of plastics is low. That’s the reason why they meltdown when they are brought in contact with the heat.
Electrical conductivity: Plastics are good insulators or bad conductors of electric current. This property or characteristic of plastic makes them popular in the manufacturing of switches, bulb-holders, the outer covering of the wires, etc.
