EVA solar film extrusion line:
Automatic gravimetric feeding system makes sure variety of solid, liquid additives and raw materials high-precision feeding.
Low-temperature extrusion systems to ensure adequate mixing in the premise of plastination to prevent crosslinking additives.Special design of Casting part give the perfect solution to roller adhibition and water spalling.
Special online tempering device to get rid of inner stress. Tension control system ensure the flexible sheets conveying placidly during cooling , pulling andwinding process.
The on-line thickness measuring and defect inspecting system can provide real-time feedback of the production quality of EVA solar film.
PVB/SGP/EVA film is a thermo-plastic film made of PVB/SGP resin and plasticizer. It is widely used for interlayer of construction glass, automobile, solar photovoltaic glass, bullet-proof glass, sound proof glass, etc. Features high safety, sound proof, ultravio let-proof, and can be colorful or super transparent, and used for construction wall glass for more than 70 years. Also it is of Optical application value, and solar photovoltaic as well.
There are two types of production method: by roller forming and water cooling forming, the thickness of final product will be 0.38-1.52mm, width will be 500-3400mm, transparent, color strip and full color film are optional.

EVA/POE film is used for encapsulation of solar photvoltaic power station, building glass curtain wall, automobile glass, functional shed film, packaging film, hot melt adhesive and other industries.
PVB/SGP film: is widely used in building sandwich glass, car sandwich glass, bulletproof glass etc. With good safety function and prevent glass from breaking due to the effect of external force and shards spatter injury; with sound insulation, anti-ultraviolet function, can be made of color or high transparent film.

Parallel twin screw extruder - EVA/POE solar encapsulation film production line
Compared with the traditional single-screw photovoltaic film production line, the co-rotating parallel twin-screw extruder line adopts innovated processing method,instead of using pre-mixed static process. The whole line is equipped with an automatic metering system, which feeds EVA/POE, cross-linking agent and other additives in a branch way, and completes the mixing and extrusion in the twin screw. At present, it is equipped with an ultra-high torque 135 main engine, and the specific torque reaches the cutting-edge level in the industry. The ultra-high torque equipment makes the average shear of the material lower, retaining more physical properties, and with the unique screw combination design and appropriate speed, it brings large output while reducing shear, preventing EVA/POE from cross-linking during the extrusion process. The whole line has a high degree of automation and low energy consumption , which can bring higher economic benefits to the customers.
