Introduction Expandable polystyrene is also known as foamed polystyrene. White beads, relative density 1.05. Low thermal conductivity, small water absorption. Shock and vibration resistance, heat insulation, sound insulation, moisture, damping. Excellent dielectric properties.
The production process Itcan be prepared by suspending polymerization of styrene and adding foaming agent.There are two processes: extrusion or steam molding. The one-step extrusion route utilizes direct hot extrusion of the material after foaming, and this method is most commonly used for sheet and film manufacturing. The two-step steam molding method is to pass the foaming agent through polystyrene particles during or after polymerization. The particles are then heated by water vapor to a temperature higher than its glass conversion temperature, so that they expand about 40-80 times, forming a honeycomb and then being molded. Use It has good heat insulation and vibration absorption, high compressive strength, very light weight and moisture resistance, can be used for building side wall and inner wall of heat insulation and sound insulation.
