Thanks for telling us it's Vespal, I had no idea what it was, now I know! 
This high performance polymer is mostly used in aerospace, semiconductor and transportation technology. It combines heat resistance, lubricity, dimensional stability, chemical resistance, and creep resistance, to be used in hostile and extreme environmental conditions.
Unlike most plastics, it does not produce significant outgassing even at high temperatures, which makes it useful for lightweight heat shields and crucible support. It also performs well in vacuum applications, down to extremely low cryogenic temperatures. However, Vespel tends to absorb a small amount of water, resulting in longer pump time while placed in a vacuum.
Although there are polymers surpassing polyimide in all of these properties, the combination of them is the main advantage of Vespel.
Thermophysical properties Vespel is commonly used as a thermal conductivity reference material for testing thermal insulators, because of high reproducibility and consistency of its thermophysical properties. For example, it can withstand repeated heating up to 300 °C without altering its thermal and mechanical properties.

i wonder if these will have any affect on the clips of the track?
