Termoreaktiivse

Termoreaktiivse refers to a type of plastic, also known as thermosetting plastic or thermoset. These plastics undergo an irreversible chemical change when they are heated and cured, forming a strong, cross-linked molecular structure. This process is often initiated by heat, but can also be triggered by a catalyst or radiation. Once cured, thermosets cannot be remelted or reshaped by applying heat, unlike thermoplastics. This permanent molecular structure gives thermosets excellent mechanical properties, including high strength, rigidity, and thermal stability. They are also resistant to chemicals and solvents. Common examples of thermosetting plastics include epoxy resins, phenolic resins, polyester resins, and polyurethane. These materials are used in a wide range of applications, such as in adhesives, coatings, composite materials, electrical insulation, and durable goods like cookware handles and automotive parts. The curing process is a critical step in the manufacturing of products made from thermosetting plastics, as it determines the final properties of the material.
