II. Advantages of Twin/single Screws Extrusion Line for XPS:

• XPS board extruded with low density (28Kg/m3).
• Big output (BHSD-65/150: 250-300/24 m3hr; BHSD-75/160: 350-400/24 m3hr).
• Accurate control of temperature and drive, with high efficiency and low energy consumption.
• Good quality of finished XPS foamed boards (good flatness, excellent closed pore, good honeycomb texture, high compression strength).
• Easy controlling system designed, with less errs happen.
