The type of plastic that cannot be reformed once set is Thermosetting.

Here's why:

1. Plastics are generally divided into two types: Thermosetting and Thermoplastics.

2. Thermoplastics are plastics that can be repeatedly melted and reshaped. They soften when heated and harden when cooled. This process can be repeated.

3. On the other hand, Thermosetting plastics are plastics that harden after being heated and shaped, and cannot be softened again. This is due to the chemical changes that occur during the heating process, which are irreversible.

4. Therefore, once Thermosetting plastics are set, they cannot be reformed, unlike Thermoplastics.

5. The terms Plasticity and Plasma are not types of plastics. Plasticity refers to the ability of a material to deform under stress without breaking, and Plasma is a state of matter, like solid, liquid, and gas.
