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
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
