It prevents the conduction of heat or even conduction of electric current shock in electric saucepan.
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.
Obviously, not all saucepans have plastic handles, but most saucepans have insulating handles - wood is another common material - so that they can be safely picked up when the rest of the saucepan is hot.
The black plastic used in plastic handles are a thermosetting plastic, typically Bakelite. Many other types of plastic, called thermoplastics will wilt and deform on heating.
To prevent electrocution
A copper bottomed pan conducts heat much better and more evenly than steel or aluminum and a plastic handle does not; making it nice and cool to handle.
That is the correct spelling of "saucepan" (a cooking pot, usually with a handle).
Plastic is a good insulator of heat, meaning heat can't flow through it very well. So a plastic handle on a kettle doesn't conduct heat through it and this means you don't get burnt when handling it.
The handle is made out of plastic.
get the strongest glue in you town and then glue it back together
to prevent the cooker or chef from burning his or hers hands.
There is a cap covering a screw in the middle of the door handle plastic, remove the cap then remove the screw. Next you need to slide the door handle plastic to the left or the right (I am not sure ) until it becomes loose. Then pull out the side with the power locks switch and disconnect the connector. Then swing the plastic all the way out so you can disconnect the rod for the door handle. This is done by sliding the plastic clip off of the top of the rod then pulling the rod up...
A good conductor of heat is metal as it has free electrons that can also carry Energy aswell as the partials themselves. This can be used for a radiator so the room can be heated. A bad conductor of heat is polystyrene. This can be used for plastic cups so the drink stay hot longer.
