Silicone Rubber Membrane For Solar Modules Lamination - The 5th Generation

Silicone Rubber Membrane For Solar Panels Lamination

Silicone rubber membrane, also called silicone rubber sheet or silicone diaphragm, is applied for the lamination process of solar modules. During the laminating period, silicone rubber membranes transfer the laminator’s temperature and pressure to modules. The silicone membrane works at least 10,000 laminating cycles with good EVA-resistant ability, even more than 10,000 times for some solar laminators.

The 5th Gen is an extraordinary type of rubber sheets, specially developed rubber membrane consisting of a silicone backing material and a unique covering layer. This covering layer is extremely resistant to outgassing* and related decomposing processes of EVA films. This makes our membrane particularly durable and increases your machine running times.

Product descriptions and advantages

*1 piece seamless sheet width up to 3800mm wide (no weak joints or marks on lay-up)

*Good cycle life - more than 10,000 cycles

*Good reusability&durability when exposed to high pressures&elevated temperatures: +250°C

*Special fluorine covering layer (black) on silicone backing (grey)

*Bond of the two layers cannot be separated mechanically

*Black covering layer is resistant to decomposing EVA outgassing* during the lamination process

*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.

How long should a membrane last?

This is really very subjective as operating conditions and controls can be very different from company to company. Whilst we quote a guide of 10,000 cycles, due to the many elements beyond our control in the installation & operating environment, it is very difficult to guarantee an exact life cycle.

Technical Data:

Silicone Rubber Membrane For Solar Modules Lamination

It has an EVA resistant fluorine laminated surface with additional fabric reinforcement.

Structure

1# Black EVA resistant fluorine - working layer

2# Grey silicone

3# 1 Ply premium aramid fabric reinforcement

4# Grey silicone - buffering layer

Standard dimensions

During the lamination/encapsulation process of EVA volatile outgassing occurs. 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 Sheets. This corrosion manifests itself in surface degradation (cracks) + excessive stretching and sagging.

Deer Hunter's 5th gen silicone rubber membrane is a hybrid material that resists the deterioration caused by EVA outgassing. In addition, it is a really tough material with both tensile strength and tear resistance higher than traditional Membranes materials.

It has very tight elongation features – resistant to excessive stretching and sagging. Customers feedback indicates that our silicone sheets may give up to 50% longer life than some traditional Diaphragm materials – obviously dependent upon the type of module, encapsulant and conditions.

Silicone rubber membrane for the lamination of solar panels, Deer Hunter can choose from a variety of laminator brands and types. Depending on the solar module production line requirements, a solar panel laminator from 3S, Meier, Bürkle, Komax, Electro Solar, or others is integrated.
