EVA Resistant Silicone Rubber Membrane Sheet For Solar Module Laminator With 10000 Life Cycles
EVA Resistant Silicone Rubber Membrane Sheet For Solar Module Laminator With 10000 Life Cycles
Although also called diaphragms, sheets, or membranes, the solar panel industry tends to use the term membrane.
In direct response to the particular needs of the solar industry, Deer Hunter developed the 2nd Generation Silicone Diaphragm. Our grey, durometer 55 silicone also remains a popular option for many solar panel manufacturers.
Specifically designed to resist the deterioration caused by EVA-outgassing, the Fifth Generation is used around the world by the leading producers of both thin-film and crystalline solar panels.
Building on their success, WE continue to research and develop products specific to the various industries they serve.

Membrane FAQs
What’s the best diaphragm 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 diaphragm.
What can we do to extend the life of our diaphragm?
Consider protecting it with a layer of PTFE sheet between the modules and the diaphragm. 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 diaphragm.
