👉 The etc fluid, also known as ethylene tetrafluoroethylene (ETFE) fluid or ETFE sheeting, is a lightweight, transparent, and highly durable material used in various applications such as construction, architecture, and transportation. It's composed of ethylene tetrafluoroethylene polymerized into a transparent, elastic, and nearly indestructible form. This fluid has a low density, making it extremely lightweight, and its high tensile strength allows it to support significant weight while remaining flexible. The ETFE fluid is also highly resistant to UV radiation, weathering, and environmental factors, ensuring longevity and minimal maintenance. Its transparency allows for natural light penetration, reducing the need for artificial lighting, while its insulating properties enhance energy efficiency. ETFE fluid finds use in roofing, cladding, and geodesic domes, offering both aesthetic appeal and functional benefits.
