In this page, I’d like to introduce more details about our The 2nd Generation silicone rubber sheet for solar panel industry.
In the lamination process of solar panel production, the workers 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 films (typically 145-155°C). That’s why those solar module makers need our flexible, resilient, and durable silicone membrane sheets specially designed for use in solar laminators to provide compression on the photovoltaic panels in repeated cycle life.
The 2nd Gen is our original & most popular silicone rubber sheet quality – combining hi-elongation, good life cycle performance under controlled environments and very competitive pricing. It is an irreplaceable element applied for the lamination process of solar PV panels and is available with both sides smooth or single-sided fabric impression surface finish.

The 2nd Gen gray silicone diaphragm is our well-proven standard product. Look at the right image to get a clear view of its structure.
Deer Hunter’s grey solar membranes are well-known throughout the industry for their consistency and durability. With high tear and temperature resistance, these diaphragms are used worldwide on various solar module laminators.
Before sending an official inquiry to us, customers may have some doubts about our silicone rubber membrane. Here we list the most common RFQ for you.
In our factory our super-wide calandars ensure that you can install our silicone rubber sheet with no seam marks visible on the back sheet to produce solar photovoltaic modules. More and more customers are placing our silicone membranes for their solar module laminator.
We find the question of surface finishes interesting - but in conclusion, we see no evidence that one option is better than another. Common sense says that a fabric impression will provide a natural venting path to aid release, especially in hot/sticky conditions. Most of our customers do prefer fabric impression 1 side and smooth 1 side. The physical properties of the material will be exactly the same irrespective of colour or surface finish - these do not change.
During the laminating period, silicone membranes transfer the laminator's temperature and pressure to modules. To give extended life in a solar panel laminator, a layer of PTFE coated fiberglass faric sheet between the modules and the membrane is often suggested. Usually thickness can be 0.25mm or 0.35mm.
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.
Commonly our data shows that The 2nd Gen upto 4,000 laminating cycles and The 5th Gen upto 10,000 cycle life. As there are a number of variables beyond our direct control, it is very difficult to “guarantee” an exact cycle life.
For 1-5pcs, standard package is woven bags. When quantity is over 5pcs, they will be rolled inside a cardboard tube and then put onto pallets or into wooden cases. We will listen to our customers carefully.
Based on feedback from customers worldwide, we can see no advantage or disadvantage of different colors. Actually, colors are now used to differentiate between suppliers.
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 Diaphragm/Membrane. This corrosion manifests itself in surface degradation (cracks) + excessive stretching & sagging.
Although also called diaphragms, sheets, or membranes, the solar panel industry tends to use the term membrane.
