Saint-Gobain Surface Solutions- Composite CHEMFILM General Purpose Fluoropolymer Film ETFE-E2

ETFE-E2 fluoropolymer film is manufactured from a copolymer of ethylene and tetrafluoroethylene resin. ETFE-E2 grade is a general purpose ETFE film fit for use in most applications. This material combines the outstanding chemical and thermal flexibility of fluoropolymer with the improved mechanical performance of advanced engineering grade plastics. The resistance to chemicals and weathering, low flammability, and stress crack resistance make this film an excellent candidate for a wide variety of applications. Weatherable Applications Saint-Gobain's ETFE-E2 film offers excellent mechanical properties and tear resistance. The high light transmission (> 94%) of ETFE film, when combined with its excellent mechanical and chemical properties, provides excellent performance in architectural roofing designs and greenhouses. ETFE film is also an excellent choice in solar collector applications due to its outstanding physical properties and high coverage factor resulting from its low density. ETFE-E2 film is UL listed under file number QMFZ2.E311412 Low Surface-Energy Applications Saint-Gobain's ETFE-E2 film offers a low surface energy, making it an excellent choice for release applications up to 165°C (330°F) process temperature. The low density of this material, compared to Saint-Gobain's FEP film, provides greater coverage per pound for composite molding release film applications. The low surface energy of ETFE can also be utilized in applications such as wall coverings and anti-graffiti protection for high traffic areas. Fabrication Capabilities ETFE-E2 film offers processors excellent dimensional stability for secondary processing such as thermoforming and welding. Products utilizing Saint-Gobain's surface treatment technologies, such as C-treatment, improve bondability characteristics for protective laminations and adhesive coating.
