WebMar 18, 2024 · Properties of Polystyrene Here are some of the key properties of polystyrene: ⇒ Physical state: Polystyrene is a hard, stiff resin that is transparent and brittle. It is an amorphous material, which means it lacks a well-defined crystalline structure. ⇒ Density: The density of polystyrene is 1.05 g/cm3. WebAug 5, 2024 · Here are some of the typical mechanical specifications for high-impact polystyrene: Ultimate tensile strength: 28 MPa. Elongation at break: 55%. Flexural modulus: 1930 MPa. Impact strength (notched): 107 J/m. Heat deflection temperature: 92°C. One disadvantage of polystyrene is its poor chemical resistance. WebPolystyrene loose-fill or bead insulation typically has a lower R-value compared to the foam board. Polyisocyanurate Insulation Materials Polyisocyanurate or polyiso is a thermosetting type of plastic, closed-cell foam that contains a low-conductivity, hydrochlorofluorocarbon-free gas in its cells. bobby bones show call in number
