Development of PS techniques
Technology makes the production of polystyrene plant can produce is more prominent than the standard PS performance grade. Many of the properties of polystyrene is not and and for them, who wish to improve impact strength, you have to sacrifice the gloss. Now some new resin, the gloss of their ABS, while there is also a high degree of toughness. When some grades such as packaged foods, resistant to grease and used for refrigerating machine capable of chlorofluorocarbons (CFC) foaming agents have also been developed. Flame retardant (UL V-0 UL 5-V), high-impact polystyrene produced and widely used in televisions, commercial machinery and electrical products. These resins processing operations more easily than many flame retardant engineering resins, the price is lower.
