Because thermoplastic materials melt when they are heated !
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.
it is used for making toys it is an example of thermoplastics
Acetal is a commonly used name for a family of thermoplastics. Its chemical name is PolyoxyMethylene.Another commonly used name for thermoplastics is Hotmelt.
Whether a saucepan can be used in an oven usually depends on the type of material from which the pan's handles are made. If the pan has a wooden or plastic handle, it should not be used in an oven. Most commercially manufactured saucepans have heat resistant handles, and may be used safely at baking temperatures up to 375 degrees Fahrenheit. If there is any doubt as to the material of the handles, do not use the pan with higher temperatures - broiling, for instance, might not be safe.
Thermosetting plastics such as polyoxybenzylmethylenglycolanhydride better know as 'Bakelite' and some others.
thermo plastic is used in gloves Lego and helmlets

because poo is poo and wee is wee
Typically, saucepans are made with a heat-resistant plastic handle, because metal handles conduct heat, making it easier to get burned if the cook isn't careful.
Because it can be melted down , also it can be re-used as it can be reshaped.
so that they dont get too hot just by conduction from the metal pot
