BoPET film was developed in the mid-1950s, [6] [7] originally by DuPont, [6] Imperial Chemical Industries (ICI), and Hoechst. In 1953 Buckminster Fuller used Mylar as a skin for a geodesic dome, which he built with students at the University of Oregon. [8] In 1955 Eastman Kodak used Mylar as a support for photographic film and called it "ESTAR ...
This was rejected in favor of a $19.8 billion suit against Swissair and DuPont, the supplier of Mylar insulation sheathing. The claim was rejected in a US federal court in February 2002.[22] I am finding it surprisingly difficult to find information on fire safety for metallized boPET film.
While artillery grain dimensions might be several inches or centimeters, the standard grains of military rifle propellant were 0.085 inches (2.2 mm) long and 0.03 inches (0.76 mm) in diameter. The Army identified this military rifle propellant as Pyro DG (for diphenylamine, graphited), and 500 tons per day were manufactured by various plants ...

Resin identification code 1 Alternate 1 Alternate 2 While most thermoplastics can, in principle, be recycled, PET bottle recycling is more practical than many other plastic applications because of the high value of the resin and the almost exclusive use of PET for widely used water and carbonated soft drink bottling.

Vespel is used in high-resolution probes for NMR spectroscopy because its volume magnetic susceptibility (−9.02 ± 0.25×10 −6 for Vespel SP-1 at 21.8 °C [5]) is close to that of water at room temperature (−9.03×10 −6 at 20 °C [6]) Negative values indicate that both substances are diamagnetic.
