HYBRANCH is the world's first polystyrene born from the application of DIC's polystyrene synthesizing and hyperbranching techniques. A well-known use of XPS is the vac-formed polystyrene trays used for small portions of food that we see in the supermarket. A cost effective popular option are clear polystyrene sheets from Ariel Plastics, lightweight, durable and stronger than glass. sPS is extremely chemically resistant and has a high melting point (270 °C) and very low dielectric constant. So unfortunately, you can't rely on one temperature for all plastics. EPS is comprised of 98% air and therefore only 2% polystyrene making it a highly efficient use of raw material. Comparing this value with the crystallinity recovered during cold crystallization reveals about 5% crystallinity for the "amorphous" samples. Morphology: highly amorphous (atactic), highly crystalline (syndiotactic) Melting temperature: 270 oC (syndiotactic) Glass transition temperature: 100 oC. It is produced from solid beads of polystyrene. The interaction between graphene and PS was significantly enhanced by melt blending, which led to an increased amount of PS-functional graphene (PSFG) exhibiting good solubility in some solvents. Stochastic dynamics 40 were performed at high temperatures, and subsequently the system was cooled to liquid densities at 475 K over a period of 0.
