Deer Hunter – A leading manufacturer of silicone sheet for Solar Cell Panel Laminate Encapsulation in China.

Heat Resistant Gray Sillicone Membrane Sheet For Solar Photovoltaic Panel Laminators

Although also called diaphragms, sheets, or membranes, the solar panel industry tends to use the term membrane.

The 2nd generation is our original & most popular Silicone Sheet quality – combining hi-elongation, good life cycle performance under controlled environments and very competitive pricing. It’s available with both sided smooth or single sided fabric impression surface finish.

1# - At present, most customers prefer smooth/textured surface, so what's the distinction between smooth/textured and smooth/smooth ?

2# - But in normal working circumstances, both are nearly the same. Customers choose the best they think.

Product description and advantages

• Both sides gray color and silicone materials

• Bond of the two layers cannot be separated mechanically 
• High temperature aramid fabric inserted in the middle
• Constant quality thanks to quality management 
• Durability results in longer machine running times and thus shorter set-up times

Standard dimensions

Width:                                    Max up to 3800mm
Material thickness:            4 mm 
Fabrication even beyond the standard width

The Second Generation lamination silicone sheets are specially designed for the solar module lamination process.

Our silicone sheets are enhanced to achieve higher laminator uptime and decreased running costs.

Starting from base silicone materials, our sheet material formulation and its manufacturing process have been optimized to offer a superior product. Our solar module lamination sheets are available up to 3,050 mm wide without a splice. This offers module manufacturers with the advantage of not having seam marks visible on their backsheets created during the lamination process.

Do you need a wide silicone laminator sheet without a splice?

DeerHunter’s seamless lamination sheet enables module makers to produce modules up to 3,050 mm wide with no seam marks visible on the backsheet.

Features and Benefits:

• Seamless surface up to 3,050 mm wide
• Cycle life of over 4000 cycles *
• High temperature resistant
• Excellent elasticity and stability

Photovoltaic modules need to withstand harsh environmental conditions for long periods – 25 years or more. One of the keys to module longevity and reliability is the lamination process, which encapsulates solar cells while attaching front and back protective sheets.

Lamination Process

The lamination process involves pumping the air out of the module layers in a vacuum chamber, heating the layers to melt the encapsulant, and pressing the layers together with a flexible diaphragm or membrane to embed the cells in encapsulant and adhere the front and back sheets. The flexible membrane is attached to the top of the vacuum chamber, and a set of valves allows the space above the diaphragm to be evacuated.

There are 3 main purposes of the sheet in the vacuum process:

• To exert a uniform pressure throughout the solar lay-up.
• Removal of moisture, solvents and volatiles from curing composite layers.
• Allow encapsulant material to flow evenly throughout solar cell lay-up.
