EPS block production


What is EPS?
Expanded Polystyrene(EPS) is a thermoplastic,closed-cell ,lightweight,rigid-foam plastic. The low thermal conductivity,high compressive, strength and excellent shock absorption of EPS make it an ideal material for the application demand for which it is used.


What is the EPS manufacturing stage?
1.Pre-expansion  Polystyrene granules are expanded by free exposure to steam to form larger beads.
2.Conditioning
After expansion, there is still small quantities of  condensed steam and pentange gas in the beads.
As they cool in the silos, air gradually diffues into the pores, replacing, in part the other components.
3.Moulding
The beads are molded to form boards, blocks or customised products.
4.Shaping
After a short cooling period, the molded block is removed from the machine.And after further conditioning, it can be cut or shaped by hot wire .
5.Post production
The finished products can be laminated with metal foils, plastics, firberboard, and welded mesh as roof  and wall panel.
