ETFE Film

ETFE fluoropolymer film

ETFE Film

FLONFILM 300 ETFE film is manufactured from a copolymer of ethylene & tetrafluoroethylene. Outstanding performance is achieved over a wide temperature range: cryogenic to +165C (330F). Good chemical resistance; excellent weatherability & low flammability together with impressive stress-crack resistance make ETFE film an excellent candidate for a wide variety of applications.

Outdoor Applications

FLONFILM 300 ETFE film enjoys excellent mechanical properties and tear resistance. The high light transmission (>95%) of ETFE film when combined with its excellent mechanical properties provides unrivalled performance in architectural roofing designs & greenhouses. FLONFILM 300 is also the natural choice in solar panel applications due to its outstanding physical properties and high coverage factor resulting from its low density.

Low Surface Energy Applications

FLONFILM 300 ETFE film exhibits very low surface energy making it an excellent choice for release applications with process temperatures up to 350F. The low density of this material compared to FLONFILM 500 FEP film provides greater coverage per kilo for composite moulding release film applications. The low surface energy of our ETFE film can also be utilised in applications such as wall coverings and ant-graffiti protection for high traffic areas.

Fabrication Capabilities

FLONFILM 300 ETFE film offers excellent dimensional stability for secondary processing such as thermoforming and welding. Special surface treatments such as C-treatment can be applied to the film to improve bondability – important in metalising & adhesive coating.
