For many years, plastic has been used as an insulator for a variety of applications. Since it is a successful insulator, it is not a good conductor of heat.

There’s a reason why plastic cookware is safe to use when stirring your macaroni, or why plastic dishes and bowls don’t get too hot when they’re thrown into the microwave.

Because plastic doesn’t let heat and electricity flow through it with ease, it can be an excellent choice for protecting electrical components and systems.

In this blog we will further explore why plastics are not a good conductor of heat and the potential benefits that come from this fact.

The short answer is no

With very little free electrons, thermal conduction essentially cannot take place with plastic. Heat is generated when molecules vibrate back and forth or collide into each other, transferring thermal energy. Since the molecules inside of plastic are so closely bound together, it requires a lot more energy for them to move and vibrate. This tight bond makes it very difficult for any electricity to flow through.

Different plastics have different thermal conductivity, however

While plastics are not good conductors of heat, there are certain plastics that have higher levels of thermal conductivity than others.

There are a few synthetic polymers that have high conductivity traits and act as electrical conductors, while polyurethane and polystyrene have lower levels of thermal conductivity.

Polyurethane and polystyrene are two of the most common types of plastic used for everyday household items, due to these lower levels.
