It is a thermoplastic! :)
Thermosetting
Polypropylene is a thermoplastic material. This means it can be melted and reshaped multiple times without undergoing any significant chemical change. In contrast, thermosetting plastics, once cured, cannot be remelted or reshaped. Thus, polypropylene's properties allow for recycling and reprocessing.

the opposite to thermosetting plastic is thermoplastic
A sharpener is typically made from thermoplastic materials, such as polypropylene or polystyrene. These materials can be easily molded and reshaped when heated, making them suitable for producing various shapes and designs of sharpeners. In contrast, thermosetting plastics, once set, cannot be remolded or reshaped, which is not ideal for the manufacturing process of sharpeners.
A helmet is typically made from thermoplastic material, which can be reheated and reshaped. Thermosetting plastic, once molded, cannot be reheated and reshaped.
