    Expandable Polystyrene (EPS)
    Product Introduction:
    EPS (Expandable Polystyrene) is made through polymerizing styrene units in suspension method by adding certain amount of foaming agent. It is white small particles with good heat insulation and vibration absorption, high compression strength, light masses and good moisture resistance. It could be processed into various thermal and sound insulating materials used for refrigerator house, central air conditioning system and buildings. Furthermore, EPS also has a broad development prospect in terms of road and bridge construction, mould process, aquatic products preservation, bill boards of advertisements, cabinets and shelves for commodities, and disposable dinnerware.
