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.
