“…Cell size, which is defined as the wall-to-wall diameter of the gas bubbles in foamed plastic, is one of the fundamental parameters that characterize its mechanical and physical properties. In connection with these factors, the fact that mechanical, optical and thermal properties of foams are highly influenced by the cell size has been reported [16].…”

In order to produce low-density crosslinked foam of superior properties having a uniform cell structure from POEs/LDPE blends, the crosslinking efficiency of resin, behavior of crosslinking sensitizer, mechanical properties according to the irradiation dose, and compressive strength in different cell sizes have been examined. When POE/LDPE (70/30) was irradiated at 3 Mrad, the gel content was 18.5%, but the addition of 0.3 phr of TATM only increased gel content up to 36%. The lower the melt index of the resin, the more the gel fraction increase was confirmed. Although tensile strength increased up to a certain point in proportion to the gel content, the decrease of tensile strength was observed over the fixed gel content. The effect of polyfunctionality was investigated by analyzing the gel fraction in accordance with the number of double bonds in molecules of crosslinking sensitizers. As a result of the measurement of changes on compressive strength according to the sizes of different foam cells, having the same degree of density, bigger cells showed stronger compressive strengths when compressed at 25%, while foams containing smaller cells showed superior compressive strengths when compressed over 50%.

A series of high impact polystyrene (HIPS) specimens was prepared under different processing conditions to study the effects of CO2 sorption and annealing conditions on thermal response and mechanical properties of gasified and/or foamed materials. The process variables included gas-saturation, non gas-saturation, foaming temperature and annealing temperature. In this study, samples were first saturated with CO2, foamed if necessary then desorbed, and finally followed by sub-Tg annealing. The thermal response and mechanical properties followed the opposite trend of materials which were first sub-Tg annealed then exposed to CO2 performed by previous workers. This suggests that gas sorption and annealing produce opposite effects. Gas sorption followed by annealing may annul a portion of the gas sorption effect, and vice versa. The glass transition temperature is an important factor that affects the trend of the results of mechanical properties in the foamed then annealed materials.
