Handles of frying pans are made of plastic why ? If you’ve ever accidentally touched the metal rim of a hot pan while cooking, you know how quickly heat travels. Yet, you can safely grip the handle to flip an omelet or stir a sauce. Have you ever wondered handles of frying pans are made of plastic why?
In Class 8 Science, we explore the properties of materials to understand how they interact with heat. Let’s break down the scientific reasons behind this common kitchen design.

Handles of frying pans are made of plastic why ?
1. Plastic is a Poor Conductor of Heat
The most important reason is thermal conductivity. Metals like aluminum, copper, and stainless steel are used for the base of frying pans because they are excellent conductors—they transfer heat from the stove to your food quickly.
In contrast, plastics (specifically thermosetting plastics like Bakelite) are insulators. They do not allow heat to flow through them easily. By using plastic for the handle, the heat from the pan is “blocked,” keeping the handle cool enough for you to hold.
2. Resistance to Melting
Not just any plastic will do. The handles are usually made of Bakelite, a type of thermosetting plastic. Unlike ordinary plastics that melt when heated, thermosetting plastics:
- Maintain their shape at high temperatures.
- Do not soften once they are set.
- Provide a durable, heat-resistant grip.
3. Safety and Comfort
Aside from heat resistance, plastic handles offer other practical benefits:
- Grip: Plastic can be molded into ergonomic shapes that fit the hand comfortably.
- Weight: It is much lighter than metal, making the pan easier to maneuver.
- Non-reactive: It won’t rust or corrode when exposed to water and steam in the kitchen.
Conclusion
So, handles of frying pans are made of plastic why? It all comes down to safety. By using an insulating material like plastic, manufacturers ensure that while the pan gets hot enough to cook your food, the handle stays cool enough to protect your hands.
