Sinopec PS resins for building heat insulators have high molecular weights and a suitable molecular weight distribution, resulting in high melt strength, good mechanical properties, and excellent processability. It is characterized by stable extrusion output and fine, evenly distributed pores during extrusion foaming.
PS resins for building heat insulators are mainly used to produce PS thermal insulation sheets through extrusion foaming. The products made from it are widely used in thermal insulation of the building industry.
