In 1997, GE Plastics and Bayer AG announced that they were forming a joint venture with an initial investment of 40 million dollars to develop and market polycarbonate materials that could be used to replace glass for automotive side windows. 15 years later in 2012 the Fiat 500L became the first car to use polycarbonate side window glazing.

If you did not watch Mythbusters religiously as I did, give the short video above a watch. It is an excellent demonstration of how a normally non-flammable material can become extremely combustible if the circumstances are right.
Although nylon 6/6 is much more commonly used than polyester (PBT) for injection molding applications, you might be surprised that these materials are relatively similar in properties.
There are, however, a few differences that might make one or the other better for a particular application.
