Tensile Membrane Material
ETFE is a transparent film made from a copolymer of ethylene and tetrafluoroethylene, with an elongation rate of 420%-440%. Its light transmission is similar to glass, earning it the nickname “soft glass.”
Types and Thickness:
Available in transparent, matte, colored, and dotted varieties. Common thicknesses are 150μm, 200μm, 250μm, and 300μm, with 250μm and 300μm being the most used. Can be used in single-layer or multi-layer cushion systems.
Main Benefits:
Durability: Lasts 25-35 years, ideal for permanent roofs. Resistant to weather, maintains transparency and strength, and is recyclable.
Heat Resistance and Safety: Fire rating B1 and DIN 4102, does not drip when burning.
Light Transmission: Up to 95% light transmission, great for solar protection and agricultural use. Can be printed to reduce transparency to 50%.
Non-Stick and Anti-Fouling: Resistant to dirt and easy to clean with rainwater.
Chemical Resistance: Inert to many chemicals, including strong acids and bases.
Key Benefits: Can be made into any size and shape for large spans without extra supports. Inflatable, allowing adjustment of shading and light transmission, saving energy and providing insulation.
