Termoplastični in termosetni polimeri

Skala, Nastja (author), Kogej, Ksenija (mentor)

V današnjem času si ne moremo predstavljati življenja brez polimerov. Te lahko delimo glede na termično obnašanje na dve skupini: termosete in termoplaste. Termoplasti pri segrevanju postanejo plastični in jih lahko preoblikujemo, za razliko od termosetov, ki pri segrevanju postanejo togi in jih ne moremo več preoblikovati. Uporabljamo jih za izdelavo cevi, kablov, folij, oken, tesnil, kopalniških kadi, električnih napeljav in še bi lahko naštevali. V tem delu podajamo pregled značilnosti termosetov in termoplastov ter njihove uporabe.

Abstract

Today, we cannot imagine life without polymers. These can be divided according to thermal behaviour into two groups: thermosets and thermoplastics. Thermoplastics become plastic when heated and can be reshaped, unlike thermosets, which become rigid when heated and can no longer be reshaped. We use them to make pipes, cables, foils, windows, seals, bathtubs, electrical wiring and we could list more. In this work, we give an overview of the characteristics of thermosets and thermoplastics and their applications.
