Solar Diaphragms

Solar Diaphragms | Smartech

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

In direct response to the particular needs of the solar industry, Steinbach developed the Lamibran® diaphragm. Steinbach’s 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 Lamibran® is used around the world by the leading producers of both thin-film and crystalline solar panels.

Building on their success, Steinbach continues to research and develop products specific to the various industries they serve.

Diaphragm FAQs

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.

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.

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 Lamibran® diaphragm that is resistant to the outgassing from the EVA. The Lamibran® option may give you far better life than your current diaphragm.
