EPS’ mechanical and physical properties

 The studied properties of a material must be related to the actual working conditions. Which are the following: Density; One of the main properties of Expanded Polystyrene that makes it attractive as a light filler is its low density, which is between 12 Kmm3 and 48 Kmm3. It is shown that the stress increases linearly until reaching the elasticity limit (1.5 to 2.0% deformation), which depends on the density of the material. When permanent deformation occurs

Effect of temperature; The deformation of the EPS occurs when the molecular chains are adjusted. If the thermal energy is increased, the speed also increases. When there is an increase in the activation of the energy in the air molecules, the speed of the movement will be greater of change that allows molecular rearrangements.
