Silicone Rubber Sheet For Solar PV Panels Laminating Machine

As one of our traditional diaphragm materials for solar modules lamination, the 5th Gen has gained in popularity over recent years for its good eva resistant ability.

Silicone Rubber Sheet - The 5th Gen

Because . make the difference

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

*EVA 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.

Product Overview

Silicone rubber sheet, also called silicone rubber membrane or silicone diaphragm, is applied for the lamination process of solar photovoltaic modules. During the laminating period, silicone sheets transfer the laminator’s temperature and pressure to modules. Thanks to its excellent physical and chemical properties, The 5th Gen silicone rubber sheet can work at least 10,000 laminating cycles with good EVA-resistant ability.

Structure

The 5th Gen silicone rubber sheet is an exclusive laminate produced from a unique pressed composition giving extended life in crystalline solar panels production. Look at the right image to get a clear view of its structure.

Due to possessing excellent EVA resistant fluorine laminated surface and additional fabric reinforcement in the middle, the 5th Gen is a really tough material with both tensile strength and tear resistance higher than traditional membranes materials. It also has very tight elongation features – resistant to excessive stretching and sagging.

Frequently Asked Questions

Before sending an official inquiry to us, customers may have some doubts about our silicone rubber sheet. Here we list most common RFQ for you.

Silicone Rubber Sheet For Solar PV Panels Laminating Machine (The 5th Generation)

As a leading silicone membrane supplier in China, Deer Hunter’s seamless lamination silicone membrane sheet enables photovoltaic module makers to produce panels up to 3800mm wide with no seam marks visible on the back sheet.

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.

What can we do to extend the life of our sheet? 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 4,000cycles and The 5th Gen upto 10,000 cycles. 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.
