Polystyrene thermal properties

WebApr 24, 2024 · Thermoplastic. One of Styrofoam’s main physical properties is that it is a thermoplastic. This means that the material is solid at room temperature, but flows as a liquid when heated to a specific point. As a liquid, the Styrofoam can be molded in fine detail. This property makes it easy to utilize for many industries and applications. WebMay 26, 2024 · 1) Polystyrene has a high thermal resistance. Extruded polystyrene (XPS) and expanded polystyrene insulation (EPS) contain millions of air pockets trapped within the foam. Because the polystyrene itself is also highly resistant to heat, the result is a great thermal insulator which can give excellent R-ratings.
