SABIC Innovative Plastics' Lexan
F6000 sheet delivers color and texture retention after thermoforming and
provides durability for the demanding public rail environment. The material
complies with railway fire protection requirements:† UL94 V0 at 1.5 mm flame retardance according
to ASTM E162, low smoke (ASTM E662) and toxicity (BSS 7239 and SMP 800 C)
Lexan F6000 sheet offers a number of important
advantages over traditional SMC for window frames. First, it is significantly
cost-effective, even though only the periphery of the sheet is used, the center
portion is recycled. Second, by streamlining the production process, the SABIC
Innovative Plastics material cuts cycle times by up to 80 percent vs. SMC.
Molded-in color avoids the need for secondary operations such as painting and
sanding; thermoforming does not require gluing or hand work; and the material
does not need a curing step - all of which were required with SMC frames.
Lexan F6000 sheet also offers sustainability
advantages over SMC, including reduction of volatile organic compound (VOC)
emissions associated with conventional painting and curing. Because Lexan F6000
sheet is approximately 30 percent lighter than traditional SMC, window
frames for railway carriages made with the material can potentially contribute
to fuel conservation.†
This opaque PC sheet is produced
with a special, durable texture that avoids the appearance of abrasion and
fingerprints, helping to maintain an attractive appearance under heavy use
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
