PTFE fabric is a type of non-porous, heat-resistant material comprised of fiberglass that has been steeped into PTFE. This type of fabric is often used in the manufacture of solar PV panels as a protective covering due to its heat resistance property and non-stick nature.
PTFE fabric also referred to as Teflon cloth or PTFE sheet, is a strong and durable synthetic material composed of a substrate made from fiberglass that is coated in polytetrafluoroethylene (PTFE). The result is a highly resilient and non-stick surface with great dimensional stability, enabling machines to function more effectively and efficiently. Durable and long-lasting when exposed to high temperatures, PTFE coated fabrics can help reduce production downtime.
Deer Hunter offers PTFE coated fabrics that are perfect for protective lamination of solar panels. These sheets are resistant to water, corrosion, and heat, making them a reliable choice for long-lasting solar module construction. With their superior quality and resistance properties, these fabrics will ensure the durability required for your projects.

Main function of PTFE coated fiberglass fabric is to prevent the melted EVA from sticking to the rubber plate and the heating plate. Once the EVA residues are stuck, it will be difficult to remove.
PTFE coated fabric is a crucial component in solar panel lamination. It acts as a protective barrier between the laminating side and the solar panel itself, preventing EVA film from melting and adhering to the surface of the laminator. Otherwise, EVA particles would melt under the sun’s heat and interfere with a photovoltaic’s function.
It is recommended that two sets of PTFE fabrics are prepared for use so one can be cooled down while the other is active; additionally, EVA particles should be brushed off after use to maximize its lifespan.
