Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. [47] It is usually white and made of pre-expanded polystyrene beads. The manufacturing process for EPS conventionally begins with the creation of small polystyrene beads.
Learn about the density, strength, melting point, and thermal conductivity of polystyrene, a synthetic polymer derived from benzene and ethylene. Polystyrene can be solid or foamed, and has various applications as insulation and packaging material.
Density: The foaming process introduces tiny air pockets into the polymer matrix, significantly reducing the material’s density. This characteristic makes polystyrene foam lightweight and buoyant, a useful feature in applications such as flotation devices and packaging material.
The thermal conductivity of expanded polystyrene foam of density 20 kg/m 3 is 0.035 – 0.037 W/(m·K) at 10°C. ASTM C578 is a Standard Specification for Rigid Cellular Polystyrene Thermal Insulation. It addresses the physical properties and performance characteristics of EPS foam as it relates to thermal insulation in construction applications.
Expanded polystyrene (EPS) foam is popular for insulation, packaging, and disposable food containers. The following table provides a comprehensive list of polystyrene (PS) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
16 kwi 2024 · Expanded Polystyrene Density is the measure of how much mass is contained within a given volume of Expanded Polystyrene (EPS) foam material. It essentially tells us how densely packed the foam is, which affects its strength, insulation properties, and its suitability for various applications.
1 lut 2019 · Polystyrene foam (EPS) is a widely used industrial material in road construction, automobile, architecture and so on [1, 2]. Compared with non-foamed polystyrene plastics, EPS has a lower density, a lower thermal conductivity and a higher loading bearing strength per weight [3].
