The development history of expandable polystyrene

 

Expandable polystyrene has the advantages of low relative density, low thermal conductivity, low water absorption, shock and vibration resistance, heat insulation, sound insulation, moisture-proof, vibration reduction and excellent dielectric properties. It is widely used as shock proof packaging materials for mechanical equipment, instruments, household appliances, handicrafts and other easily damaged valuable products as well as fast food packaging.

As a thermoplastic foam, expandable polystyrene has experienced a long development process. In 1925, Germany began to produce styrene, which was used as a rubber intermediate and laid the foundation for the production of polystyrene. In 1930, the suspended PS came out. In 1943, the American DOW Chemical Company took the lead in putting PS foam into industrial production. In 1949, Japan successfully developed extruded polystyrene foam (XPS) and used it for product packaging. In 1952, EPS products first appeared at the German Plastics Trade Fair.

Our company-Leili Chemical Co.,Limited specializes in the production of expanded polystyrene series products, including flame-retardant expanded polystyrene, fire-resistant expanded polystyrene and so on.
