Clear, lightweight polycarbonate sheet for aircraft interiors

Sabic Innovative Plastics : 15 April, 2014  (New Product)
Launched at the Aircraft Interiors International Expo (Hamburg, Germany, 8-10 April 2014), Lexan XHR2000 sheet and Lexan Light F6L300 sheet will meet airlines’ desire for differentiated cabin interior designs while also helping to take out significant weight.
Aircraft interior designers are often restricted by the clarity and compliance limitations of the transparent materials currently available to them. With 80% light transmission – the highest level of light transmission available in an OSU-compliant sheet material – Lexan XHR2000 sheet is a pioneering option for aircraft interiors with this level of transparency, while still meeting OSU 65/65 heat release and typical industry flame, smoke, toxicity (FST) requirements (FAR25.853, BSS7239, ABD0031).
Robust vertical burn performance is also possible with the use of a post-secondary process, such as a functional coating or laminated film, which adds further design, chemical resistance and scratch resistance properties. Lexan XHR2000 sheet facilitates the design of large components such as security partitions and oversized windows, which are becoming increasingly popular in top deck designs. Additionally, it enables future innovation, helping designers find answers to unmet needs, such as the evolution of self-service refreshment stations on aircraft which require large transparent windows so that passengers can see what is available. Other potential applications include partitions, dust covers, instrument displays, entertainment screen partitions and divider panels, galley equipment panels, protective panels, stairs/railing panels, barriers, windows, mirrors, lighting lenses, door and refrigeration systems and printed, custom laminated applications that require transparent/translucent graphic designs.
Secondly, the patent-pending high performance Lexan Light F6L300 sheet is claimed to be the lightest thermoplastic sheet option available, regardless of base material, that complies with flame, smoke and OEM toxicity. With a specific gravity of 0.85g/cm3, it offers up to 40% weight savings when replacing traditional sheet products based on polyvinyl chloride and acrylic blend (PVC/PMMA). Potential applications include seating parts, cockpit dashboard enclosures, partitions, luggage compartments and passenger service units. Lexan Light sheets meet typical industry flame, smoke density and toxicity requirements (BSS7239, ABD0031).
Using Lexan Light sheet to replace PVC/PMMA products on seating frames can help reduce weight by approximately 122kg, based on an aircraft with average of 190 seats. This is due to the innovative closed cell structure, which can be thermoformed into complex 3D shaped parts with very thin walls, down to 0.6mm.
