handles of cooking utensils are made of plastic which are hard,strong,and rigid.plastic films are flexible and are not very hard and strong.explain why two plastics show different properties
Answers
Explanation:
Thermosetting plastics are used in saucepan handles because they do not soften on heating and also they cannot be bent easily. These plastics like bakelite are poor conductors of heat.
Bakelite is a polymer which is scratch resistant and an excellent insulator. Due to this, it is used in making cooking utensils which do not conduct heat.
Thermosetting plastics are used for making those articles which may get too hot during use and are hard and rigid.
MAIN PROPERTIES OF PLASTICS
••Most plastics are light, chemically stable and do not rust.
••Good impact resistance.
••Good transparency and wear resistance.
••Good insulation, low thermal conductivity.
••General formability, good coloring, low processing cost.
••Most plastics have poor heat resistance, high thermal expansion rate and easy combustion.
