Product Desciption

EPS(Expandable Polystyrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. 
How do we classfiy EPS Material?
Regular Grades - High Expansion, Medium Grade, Fast Cycling, Colorful beads
Flame Retardant - High Ratio Flame Retardant, Low Flame Retardant.

Fast cycling grade EPS confers excellent processing and product properties Consistent raw beads and good fluidity of foamed bead. No harmful odors in pre-expansion and moulding Short maturing time Characteristically rapid cooling and better performance with vacuum system Uniform cell size, beautiful and flat surface appearance Good integration inside, high resistance Use in contact with food Recommended 40-60 expansion ratio.

Recommended Processing Condition Material Selection Select proper bead diameters according to the required shape and density of the final product.
Large articles in medium and low density (less than 16g/l) require D-104 or D-103.
Continuous pre-expanders require D-104 or D-105 while batch pre-expanders require D-105/D-106/D-107.
Pre-expansion Steam Pressure: 0.15Mpa-0.30Mpa
Pre-expansion Temperature: 96-108ºC
Conditioning Time: 4-24 Hours
Moulding Steam Pressure of Stationary Mould: 0.7-1.2kgf/cm²
Steam Pressure of Moving Mould: 0.7-1.2kgf/cm²
