d)Refrigerators have plastic foam core as it is the most resistant to the low.it prevent heat from coming into Refrigerators
e) plastic is an insulator.it is used to prevent short circuit and prevent humans from getting shock.
f)Because it is heat resistant and it does not conduct electricity..it will not melt or deform at very high temperature
