Polystyrene xps foam board/sheet/plate extrusion line

Product Description:

Polystyrene xps foam board/sheet/plate extrusion line

　XPS foamed sheet, also named as Polystyrene Extrusion Plastic Sheet (XPS for short) has a perfect closed-pore alveolate structure. Its density, water absorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other sheet heat insulating materials and they have the characteristics of strong intensity, light material, airtight, anticorrosion, ageing resistance, low cost, etc. It has been widely used in the fields of heat preservation in the construction industry and the highway, railway, airport, square of the heat preservation and household fitment. It is the generally acknowledged and the best heat insulator in the market at present.

Part One: Quick Details for XPS production line

First, PS solid granules are fed into the primary extruder, heated and melted into viscous fluid, which is injected foaming agent (HFC, carbon dioxide, butane are optional) at the secondary extruder.

Then, under careful controlled heating and pressure, the fluid is forced through a die head where forming and shaping occurs.

Finally, the rigid foam board is cut and trimmed into required dimensions.

PART Two: XPS Production machine

1. Capacity Range: 180 - 500cubic meter per day

2. Thickness: 20 - 100mm

3. Width: 600mm,900mm,1200mm

4. Material: new GPPS, recycled EPS material, recycled PS, GPPS material

5. Vesicant: Freon:F22, F142, F143; CO2; Vacuum

6. Type: Freon type with density from 28 -40kg/m3

             CO2 type with density from 25-33kg/m3

             Vacuum type with density from 26 --31kg/m3

7. XPS prevails in insulation, moisture proof, compresive strength, durability and convenient installation.

8. We also can afford some second-hand working equipments in China market. It's more

   economical and convenient for new investors.
