Ethylene-tetrafluoroethylene (ETFE) film - this is the very light weight, heat resistant, fire-resistant and light transmitting fluoropolymer, also known as "soft glass". These features are why it is a material of high demand in different sectors, particularly in the fields of architecture and construction. These characteristics make it a highly sought-after material in various industries, particularly in architecture and construction. 

What Is ETFE?

Before we discuss ETFE film, we should first understand what ETFE is. ETFE is a fluororesin synthesized by alternating copolymerization of ethylene and tetrafluoroethylene. It was first commercialized in the late 20th century and has since become famous for its multifunctional properties. Fluorine atoms are added to its structure, giving it excellent chemical inertness and thermal stability.

ETFE products include powders and granules, which can be processed by spraying, rolling, extrusion, injection molding and other processing technologies to obtain anti-corrosion linings, films, hoses, cables and other molded parts.

Among them, ETFE film is the focus of our attention today. ETFE film material has no fabric substrate and is directly composed of thermoplastic compound film. The ETFE powder or particles are heated to above 380℃ to reach the molten state of resin slurry. It is finally shaped into a film of standard thickness and standard width through hot pressing wheel extrusion.

How Powerful Is ETFE Film?

ETFE is the toughest fluoroplastic. While maintaining the good heat resistance, chemical resistance and electrical insulation properties of PTFE, it has greatly improved radiation resistance and mechanical properties, and various mechanical properties have achieved a good balance - extremely strong tear resistance, high tensile strength, medium hardness, excellent impact resistance, and long telescopic life.
