Silicone Sheet For Solar Laminators

Silicone Rubber Membrane For Solar Module Laminating Machine and Encapsulation Line

Deer Hunter – Asia's leading supplier for speciality silicone sheets for solar panel manufacture in the renewable energy market.


Silicone Rubber Membrane For Solar Module Laminating Machine and Encapsulation Line

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


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 diaphragms are specially designed for the solar module lamination process.

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

Starting from base silicone materials, our membrane material formulation and its manufacturing process have been optimized to offer a superior product. Our solar module lamination membranes 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 membrane without a splice?

Fullchance’s seamless lamination membrane 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 3000 cycles *
  • High temperature resistant
  • Excellent elasticity and stability
* Cycle life is dependant on set up and operating conditions.


The Second Generation Silicone Membrane

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 membrane 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.

Silicone Rubber Membranes FAQs

What’s the best membrane for our application?

This is a big question and really best discussed together on the phone. Determining factors would include your type of encapsulant, composition of the modules, size of the modules, and type of laminator.

How long should a diaphragm last?

This also depends on your encapsulant and type of module. Give us a call to talk about your product and processes to determine what you should be getting from your membrane.

What can we do to extend the life of our membrane?

Consider protecting it with a layer of PTFE sheet between the modules and the membrane. We have several options for this. And if you’re encapsulating with EVA, we should discuss the fifth generation Fluorosilicone membrane that is resistant to the outgassing from the EVA. The Fifth Generation option may give you far better life than your current membrane.
