Explain why saucepan handles is made of thermosetting plastics?

Saucepan handles are not made of thermosetting plastics. They are typically made of heat-resistant materials such as metal or wood, which can withstand high temperatures without melting or deforming. Thermosetting plastics, on the other hand, are a type of plastic that undergoes a chemical change when heated, forming a rigid and permanent structure. This process, known as cross-linking, makes thermosetting plastics unsuitable for applications where high temperatures are involved, as they can become brittle and lose their strength.
