Teflon coated glass fabric is a new high-performance, multi-purpose composite material that can be used in a variety of applications. It is made up of a woven glass cloth substrate coated with polytetrafluoroethylene (PTFE) resin, which makes the fabric waterproof, durable and high temperature resistance.

This material has excellent electrical properties, chemical resistance, and fire retardancy. Additionally, it can remain flexible in cold temperatures and has a low surface energy that limits adhesion from various contaminants.

Teflon coated cloth is available in custom sizes and roll lengths to fit your exact needs. It can also be cut or manufactured to order.

Properties of Teflon Glass Fabrics

Teflon fabric, also known as PTFE fabric, is an ideal material used in solar cell laminating machines. It consists of high quality glass fabrics and PTFE. These materials create a super smooth and high-gloss surface coating that is resistant to wear, low friction, chemical exposure and temperatures ranging from -70°C to +260°C. The non-toxic qualities of the fabrics make it safe for use in laminating solar panels and other sensitive items.

Which kind of Teflon fabrics are used for solar panel manufacturing?

Teflon release sheets are essential in the lamination process of creating solar PV panels as protective coverings, due to their exceptional heat resistance and non-stick quality. The primary purpose of Teflon cloth is to keep the melted EVA film from attaching to the silicone rubber plate or heating plate. When EVA becomes adhered to these surfaces, removing them can be very challenging.

How to Apply Teflon Fabrics for Solar Laminator Correctly?

PTFE Cloth Laminated Sheet

Teflon cloth is a unique material with excellent heat resistance, non-stick attributes, and anti-static properties. It’s extremely durable and tightly woven, making it a popular choice for heavy-duty applications such as those found in solar photovoltaic module plants. Its special properties make it an ideal replacement for traditional materials.

Solar lamination fabrics are an important part of the lamination process for photovoltaic modules. At least two sets (4 sheets) of these fabrics are required to be used in each solar laminator. They consist of PTFE laminated cloth which acts as a protective cover and backing cloth on the module and helps to prevent the sticking of EVA and other substances to the machine under high temperatures.

PTFE coated glass fabrics are essential for effective lamination processes and are highly reusable. However, it is important to allow them to cool down before reuse in order to avoid any transfer of EVA particles from the laminated fabric. If left on the fabric, these residual EVA particles can be transferred onto the glass during re-use, leaving behind mounds of dust that can block parts of cells and create long-term hot spot effects when used outdoors.

PTFE coated glass cloth is often used as a release sheet for many laminating processes, and also as conveyor belts for specific automatic laminator machines. For these cases, the surfaces of the PTFE must be textured to ensure that there is an adequate level of friction between it and the materials being laminated. Additionally, in order to prevent damage to either the conveyor belts or material, the tension of the belt should not be too high when conveying.

Attention of Installing Teflon fabric in Solar Laminator

  • When using Teflon fabrics to protect machines from heat, it is important to keep the surface as flat as possible. This will reduce the risk of creases appearing on the laminated surface and decrease the fabric’s lifespan. Before cutting and installing Teflon sheet, make sure that any wrinkles are removed.
  • Keep your Teflon cloth looking like new with a quick wipe-down! Any EVA glue or residue that may have accumulated on the surface can be easily removed by simply using a semi-damp cotton cloth.
  • When it comes to heat-resistant Teflon fabric, slight variations in color batch-to-batch are normal. This won’t influence the quality of the product or its use in any way.

Maintenance of Teflon PTFE Fabric

Teflon PTFE fiberglass fabric is an incredibly strong and durable material that can withstand extreme temperatures, resist to most chemicals, and has a smooth and non-stick surface.

Frequently Asked Questions about Teflon Fabrics

Is Teflon the same as PTFE?

The simple answer is that they are the same thing: Teflon™ is a brand name for PTFE (Polytetrafluoroethylene) and is a trademark brand name used by the Du Pont company and its subsidiary companies (Kinetic which first registered the trademark & Chemours which currently owns it).

What is EVA material in solar panel?

EVA is ethylene vinyl acetate, a material that has good radiation transmission and low degradability to sunlight. This is a thermoplastic polymer used in solar modules as an encapsulating agent since, by applying heat to the assembly, it forms a sealing and insulating film around the solar cells.
