What Are Thermosets?

Thermosetting refers to the property that it cannot be softened and repeatedly molded when heated, and it does not dissolve in solvents. Body polymers have this property.

Thermosetting polymer (English: Thermosetting polymer)

When heated for the first time, it can be softened and flowed. When heated to a certain temperature, a chemical reaction occurs and the cross-linking solidifies and hardens. This change is irreversible. After that, when heated again, it can no longer be softened and flowed. It is based on this characteristic that the molding process is performed.

Thermoset materials will be carbonized when they are exposed to fire.

There are cross-links (covalent bonds) between the polymer chains and the chains of the thermoset plastic, so the chains and chains cannot slide with each other, and they will not soften or dissolve when heated. ^[1]
