Silicone Sheet For Solar Laminators

High Temperature Silicone Sheet For Solar Panels Laminator

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


High Temperature Silicone Sheet For Solar Panels Laminator

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

Product description and advantagese

  • Diaphragms for PV module manufacture
  • Special covering layer (black) on silicone backing (grey)
  • Bond of the two layers cannot be separated mechanically
  • Black covering layer is resistant to decomposing outgassing during lamination process
  • Durability results in longer machine running times and thus shorter set-up times
  • Constant quality thanks to quality management

The Fifth Generation Silicone Sheet is a specially developed membrane consisting of a silicone backing material and a unique covering layer. This covering layer is extremely resistant to outgassing and related decomposing processes of EVA films. This makes Lamination particularly durable and increases your machine running times.


Corrosive attack on Silicone Sheets

World-wide producers of thin film and crystalline solar panels face corrosive attacks on Silicone Sheets used on lamination equipment.

During the lamination / encapsulation process of EVA volatile outgassing occurs. Outgassing refers to unwanted chemicals that are usually a bi-product of the process and temperature. These acidic fumes are emitted from adhesive or other components and can lead to corrosion of the Sheets. This corrosion manifests itself in surface degradation (cracks) + excessive stretching and sagging.

Deer Hunter Fifth Generation Silicone Sheet is a hybrid material that resists the deterioration caused by EVA outgassing. In addition it is a really tough material with both tensile strength and tear resistance higher than traditional Membranes materials.

The Fifth Generation Silicone Sheet has very tight elongation features – resistant to excessive stretching and sagging. Customers feedback indicates that our silicone sheets may give up to 50% longer life than some traditional Diaphragm materials – obviously dependent upon type of module, encapsulant and conditions.

Silicone Sheet FAQs:


What’s the best sheet 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 sheet?

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.
