Polystyrene board is divided into two types: molded polystyrene board (EPS) and extruded polystyrene board (XPS) board. Under the same thickness, XPS board has better insulation effect than EPS board. EPS board absorbs water compared with XPS. High sex and good ductility. XPS board is a commonly used heat insulation and moisture-proof material in the construction industry. It has been widely used in wall insulation, flat concrete roof and steel roof insulation, low temperature storage, ground, parking platform, airport runway, highway and other fields. Moisture-proof insulation and control of ground expansion.
Polystyrene is a thermoplastic resin that is widely used because of its low cost and ease of processing. The polystyrene is in the form of a homopolymer (clear pellet) or a toughened graft copolymer or a blend with an elastomer (impact polystyrene IPS). Polystyrene copolymers have improved physical and thermal properties over homopolymers. These types of polystyrene are available in a variety of grades, such as standard IPS and standard transparency grades, environmental stress crack resistance grade (ESCR), and UV resistance. Flame retardant grade, wear resistant grade, high flexibility grade for lightweight parts, foamable grade, ultra-primary and low residual volatile grades. Polystyrene resin is used in the manufacture of disposable tableware, automobile parts, packaging materials, toys, building materials, electrical appliances and household goods in daily life.
