PCTFE is stiffer than PTFE, which means it lacks some of the softness of PTFE when it comes to sealing, but that it also holds its dimensions more easily. Well-suited to diverse applications. Kashyap Mistry Director - Advect Process Systems Canada Ltd // Advect Process Systems USA LLC. All the reflections correspond to the JCPDS: 873-1752 standard card for hexagonal PbI 2. []. Because of their ordered structure, semi-crystalline polymers possess characteristics such as a well-defined melting point, better strength, improved fatigue performance, good chemical resistance and improved.
