Insulation blanket made from Solvay’s Halar ECTFE film meets aircraft interior standards
Solvay Specialty Polymers stated on September 27 that Chase-Facile’s Insulfab 4000 thermal acoustic insulation blanket (TAIB) cover film,
made with Halar ECTFE film from Ajedium Films under Solvay Solexix Inc, has been qualified to meet Boeing BMS 8-377 for both Class 00 and Class 1 Types I & II and has been officially added to the Boeing Qualified Products List (QPL).
The Insulfab 4000 can be used as a replacement for the previously qualified Tedlar polyvinyl fluoride (PVF) based styles of TAIB, according to Solvay. The new product of Chase-Facile, a division of Chase Coating & Laminating, consists of a lamination of film made from Halar ECTFE (a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene), nylon fabric, and a proprietary adhesive.
Insulfab 4000 insulation film provides resistance to fire propagation in thermal acoustic insulation required by FAR 25.856(a). It also meets the requirement of FAR 856(b) which mandates resistance to flame penetration and heat release into the passenger compartment, Solvay stated.
Thermal acoustic insulation blankets are typically installed behind airplane interior panels to protect passengers, cargos, and equipment from thermal and acoustic extremes associated with environmental conditions and engine noise sources.
Ajedium Films, acquired by Solvay Solexis in 2008, is the film division of Solvay Specialty Polymers.
