What is a characteristic of thermoset resins?

Thermoset resins are a category of polymers that undergo a curing process, which transforms them into a hardened and inflexible state. This curing process typically involves a chemical reaction that cross-links the polymer chains, resulting in a material that is rigid and unable to be reshaped or remolded after it has set. Once cured, these materials maintain their structure and properties, making them suited for applications that require strength and durability.

This inability to be re-formed after curing distinguishes thermosets from thermoplastics, which can be melted and reshaped multiple times. The rigid characteristics of thermoset resins also contribute to their ability to withstand high temperatures and chemical exposure, making them ideal for various applications in manufacturing, automotive, and aerospace industries.
