termoreaktive

Thermoreactive is a term used to describe materials or substances that undergo a chemical or physical change when subjected to heat. This response to temperature is a defining characteristic of these materials. When heated above a certain threshold, a thermoreactive substance will transform, often irreversibly. This transformation can involve changes in properties such as color, shape, or chemical composition.

Common examples of thermoreactive materials include thermosetting plastics. These polymers are initially pliable and can be molded into desired shapes. However, upon heating and curing, they form rigid, cross-linked structures that cannot be remelted or reshaped. Another category includes thermochromic materials, which change color in response to temperature variations. This property is utilized in various applications, from mood rings to temperature indicators. Similarly, some metals and alloys exhibit thermoreactivity, undergoing phase changes or annealing processes at specific temperatures, altering their mechanical properties. Understanding the thermoreactive behavior of a material is crucial for its proper processing, application, and performance prediction in diverse industrial and scientific contexts.
