Because the plastic is the poorest conductor of heat (That means it doesn't heat up when it touches something that's hot). Metal is a great conductor of heat though, so if the handle were made of metal we would burn our hand whenever we touch the handle.
because if pan handle made of paper our hand can burn
Plastic is a poor conductor of heat; it doesn’t let heat flow through it. For instance, when we heat the water in a pan, we can lift the pan using the plastic handle because it doesn’t get hot, but if the same handle was of metal, we couldn’t have been to lift the pan because metal is a great conductor of heat.
The pan handle is made up of plastic because plastic is a poor conductor of heat, which means it will not heat up. Whereas metal is a good conductor of heat, which means it will heat up causing our hand to burn.
Hope it helps 😊
Since Plastic is a poor conductor of heat, It is used as the handle in pans as it does not transfer the heat from the pan to the handle and burn your hand whereas if a good conductor of heat like metal was used then the handle would heat up and give you a First or Second Degree burn.
The handles of frying pans are made of plastic or insulating materials because plastic and insulating materials doesn't allow the heat to flow from pans to handles so that it will be easy to hold the frying pans.
They are basically made of plastic or insulating materials because insulating material doesn't allow the heat to pass through the pans to handles. thus it is easier for the person to hold the handle and the person's hand doesn't also burn.
The first and last answers simply are not correct, nor do they answer your question. The second, middle question is much better, but it does not fully answer your question either.
If a metal pan with a plastic handle is put in the oven at, let's say, 350 deg., then the temperature of the entire pan, metal and plastic, will eventually reach 350 deg. It is not true that the plastic won't get hot, actually it should heat up faster than the metal.
There are two properties in consideration: heat capacity and thermal conductivity. Metals in general have large heat capacities. One can think about the amount of heat a substance can store per unit mass, called the "Specific Heat," or one can consider the amount of heat a substance can store per unit volume. In the case of a pan and handle, it makes more sense to look at the question in terms of the heat stored per volume.
Most people know from everyday experience that metals stay hot longer than non-metals like wood and plastic. That is because metals have a much larger heat capacity per volume than most non-metals; that is they hold more heat.
What about thermal conductivity? In this case, we only need to consider the thermal conductivity of air.
Heat flows FROM a hotter object TO a cooler object. If a pan w/ plastic handle is put in a 350 deg. oven and allowed to heat up completely, when it is taken out the oven the pan and handle are at 350 deg. We only need to consider the heat transfer from the metal to the air and from the plastic to the air. Since the cooler material is the air, all that matters is the thermal conductivity of the air. You can look up thermal conductivities in a table, but air, and all gasses, have much lower thermal conductivities than almost any solid, and it is certainly lower than the pan and Bakelite® (the pan's handle). Since the handle does not contain as much heat as the pan, it will cool down to a touchable temperature faster.
The same applies if the pan is placed on a burner. The handle will take longer to heat up than the metal because 1) the metal is directly over the flame, and 2) the metal has a higher thermal conductivity than the plastic meaning that a lot more of the heat from the burner will be absorbed by the metal.
Answer
The reason the pan Handle is made of plastic is because Plastic is not a conductor of heat so it won't get hot. If the handle was metal it would get very hot because it is a conductor of heat.
Answer
Frying pans have plastic handles because plastic is a terrible conductor of heat that is coming from a stove. Therefore the handle is cool even when the metal of the frying pan is hot, when you need to lift it, or perhaps something else.
Answer
Safety. Plastic will not conduct either heat or electricity, so in order you can safely handle pots and pans, plastic is used for those reasons.
Conductivity of air plays practically no role in this. If the pan heats up air in contact, that air is immediately removed by convection and replaced by cool air.
That is because when you are cooking you need to handle the pan most of the time while stirring or dodging the food you are cooking. All the pan is made up of conductive material that heats up so fast that it could burn your skin if handled bare handed EXCEPT for the handle that is made of plastic or other non-conductive material to make cooking safe and enjoyable

What are rubber stamps made of?
Rubber stamps come in many shapes and sizes. They consist of a handle, usually of wood or plastic, and the die--attached to said handle-- made of rubber or a rubber like substance.
What materials are used to make a Phillips screwdriver?
A phillips screwdriver is generally made of a steel shaft with a plastic handle
What is the handle and blades of a Phillips screwdriver made from?
The blade is metal and the handle is usually either wood or plastic.
What plastic is a pen made out of?
a plastic pen is made out of a special type of plastic that is moulded to the shape of a pen! :)
Is plastic a Man- made fabric?
yes plastic is a man made fibre
Why the handles of saucepan usually made of plastic?
Plastic conducts heat poorly, and it's waterproof. A plastic saucepan handle will allow the cook to hold the handle without using a potholder, and the pan can be washed in a dishwasher.
What part of a pan is a good insulator?
The handle of a pan is a good insulator because it is typically made of a material that does not conduct heat well, such as plastic or wood. This helps to prevent the heat from transferring to the handle, making it safe to touch even when the pan is hot.
Is the handle made out of plastic or glass?
The handle is made out of plastic.
What material is the fying pan handle made of?
The frying pan handle is typically made of heat-resistant materials such as stainless steel, silicone, or heat-resistant plastic. These materials help to prevent the handle from getting too hot to touch during cooking.
What is a kettles handle made of?
it Is Made Out Of Plastic
why is the handle of an electric iron made up of plastic or wood?
It is made an plastic
Why is the handle of a pan a good insulator?
A metal frying pan handle, covered in a good heat insulating material, means that you don't burn your hand when picking the frying pan off the stove. It also means that you don't have to insulate your hand by using a tea-towel or oven glove.
What is the scientific reason for making a frying pan with a plastic handle instead of a metal one?
The reason is to avoid burning your hands when you grab it. Plastic is a poor conductor of heat.
Why do saucepans often have plastic handles?
Plastic does not conduct heat as well as metal as a result it is not as hot to the touch making it ideal for a handle or removable lid. Plastic does not conduct heat as well as metal as a result it is not as hot to the touch making it ideal for a handle or removable lid.
Why is the handle of a screwdriver used by an electrician made of plastic?
To prevent electrocution
Is a handle of a pan a lever?
Yes, a handle of a pan can be considered a lever because it allows you to apply a force at one end (the handle) to lift or move the pan at the other end. The pivot point is where the handle connects to the pan.
Should the handle and bristle of a tooth brush be made of the same material?
no, they should not be made of same material because handle of brush is made up of plastic ,which is made up of very toxic chemicals. If bristles are made up of plastic then it will be very harmful for our health.
