| Abstract: | This paper analyzed the requirements of using speciality polystyrene(PS) resin for producing foamed sheet with extrusion process and developed a grade of the resin,680X.The molecular structure and processability of 680X and its counterpart that prevailed in the market was compared.The result indicates that 680X possesses high relative molecular mass and its appropriate distribution,exhibiting comparatively high melt strength.Its mechanical properties and processability of 680X are superior and therefore,can meet the requirements of PS foamed sheet. |
