- PS resins have very low molecular weight, low strength, and less durability when exposed to high temperatures. High durability when molecular weight increases. At a temperature of 80 degrees Celsius, the plastic will be soft and sticky like rubber.
- PS resins are only used at temperatures lower than 80 ° C.Density 1.05-1.06 g / cm³.
PS resins are widely used in many fields such as foam boxes, food trays, CDs, and so on.
