Solar Silicone Diaphragm - Then 2nd Generation

*An irreplaceable element in solar PV modules encapsulation


Solar Silicone Diaphragm Material For PV Module Lamination

Silicone diaphragm is an essential component inside the lamination process of solar modules. China Deer Hunter is providing silicone rubber diaphragm with more advantages as below:


  • resistance to high temperatures
  • outstanding chemical resistance
  • long-term flexibility
  • excellent elasticity
  • constant quality thanks to their internal quality management
  • extra large available up to 3500 mm
  • different material thicknesses
  • durability results in a longer machine running times and thus shorter set-up times


In the process of solar photovoltaic panel's lamination, the panel manufacturers encapsulate all components with ethylene-vinyl acetate (EVA) adhesive film to ensure that module layers remain secure. That will cause high heat to melt the EVA (typically 145-155°C). That's why those makers need our flexible, resilient, and durable silicone diaphragm designed for use in the solar laminators to provide compression on the PV panes in repeated cycles.


Deer Hunter has worked in partnership with the foremost solar laminator manufacturers to develop solar diaphragms that meet the specific requirements of PV module manufacturing. Here it is our great honor to introduce "The 2nd Generation Silicone Diaphragm".


The 2nd Gen is our original & most popular solar silicone diaphragm for PV panels lamination – combining hi-elongation, good life cycle performance under controlled environments, and very competitive pricing. It's available with both sides smooth or single-sided fabric impression surface finish.

1: What’s the best solar diaphragm for photovoltaic modules lamination?


A: This is really a vital question and can be best discussed together face-to-face. There is no one answer that is right for everybody. There are many determining factors that can affect the choice of silicone diaphragm for example type of encapsulant, the composition of the modules, size of the modules, the brand of laminator, and budget constraints, etc.


2: How long should the silicone diaphragm last?


A: Commonly our data shows that The 2nd Gen - 4,000cycles + The 5th Gen - up to 10,000 cycles. As there are a number of variables beyond our direct control, it is very difficult to “guarantee” an exact cycle life.


3: Does color or surface finish have any impact on membrane performance?


A: Based on feedback from customers worldwide, we can see no advantage or disadvantage of different colors, or indeed surface finish. Actually, colors are now used to differentiate between suppliers.


4: What can we do to extend the life of our sheet?

A: Consider protecting it with a layer of PTFE sheet between the modules and the membrane. We have several options for this.


5: Can you do tailor-made products?

A: We are very willing to research and develop a kind of solar silicone diaphragm for your special requests.
