Orcofilm^®

ORCON's family of Orcofilm^® is a family of high performance, reinforced, flame-retardant covering films used in aircraft thermal/acoustic insulation systems, aircraft ducting and variety of other aerospace applications.

On July 31, 2003 the Federal Aviation Administration issued the Final Rule on Improved Flammability Standards for Thermal/Acoustic Insulation Materials Used in Transport Category Airplanes (FAA 2000-7909). According to the Rule, all thermal/acoustic insulation materials installed in the fuselage of transport category airplanes have to pass a flame propagation test (Radiant Panel Test) per FAR 25.856 (a).

The rule is applicable to all transport airplanes, regardless of size and capacity, manufactured after September 2, 2005 as well as all replacement thermal/acoustic insulation materials installed on transport airplanes after September 2, 2005.

Following Orcofilm^® products meet the requirements of FAR 25.856 (a) as well as FAR 25.853 and FAR 25.853:

Some of the previous generation Orcofilm® products were designed to meet FAR 25.853 and FAR 25.855 only and do not comply with recently introduced FAR 25.856 (a). As industry is switching to FAR 25.856 (a)-compliant materials, Orcon Corporation is planning to phase out all insulation covering films that do not meet the requirements of the new FAA Rule.

If you currently use or plan to use insulation covering films that do not meet FAR 25.856 (a), we suggest you consider replacement options from the right column of the table below:
