Main PCL applications
Thermotropic liquid crystal polymers (PCL)

Although the use of PCLs is limited today compared with traditional polymers such as PBT, PET, PC, polyamides, etc., their future is promising and their potential uses much broader than they appear, as demonstrated by the growing number of developments in more and more industries (see examples, figure 19 ).

Mass reduction, the miniaturization of devices (cell phones, PCs, printed circuits, halogen spotlights, ignition systems), the rise in temperatures induced by miniaturization (as in the case of exhaust gas recycling, for example), the increased aggressiveness of chemicals (mainly resulting from higher temperatures: what used to work at 130 C no longer necessarily works at 140 C or 150 C), and increased environmental protection are all factors behind the growing...
