There are many different types of plastic, and they can be divided into two main categories: thermoplastics and thermosets. Thermoplastics and thermosets react differently to heat. Thermoplastics can be melted and reshaped multiple times without losing their properties, making them recyclable and
flexible. Thermosetting plastic hardens permanently when heated and cannot be remelted, making it more heat-resistant but more difficult to recycle.
